AB  - Wind power assessment in complex terrain is a very demanding task. Modeling wind conditions with standard linear models does not sufficiently reproduce wind conditions in complex terrains, especially on leeward sides of terrain slopes, primarily due to the vorticity. A more complex non-linear model, based on Reynolds averaged Navier-Stokes equations has been used. Turbulence was modeled by modified two-equations k-? model for neutral atmospheric boundary-layer conditions, written in general curvelinear non-orthogonal co-ordinate system. The full set of mass and momentum conservation equations as well as turbulence model equations are numerically solved, using the as CFD technique. A comparison of the application of linear model and non-linear model is presented. Considerable discrepancies of estimated wind speed have been obtained using linear and non-linear models. Statistics of annual electricity production vary up to 30% of the model site. Even anemometer measurements directly at a wind turbine?s site do not necessarily deliver the results needed for prediction calculations, as extrapolations of wind speed to hub height is tricky. The results of the simulation are compared by means of the turbine type, quality and quantity of the wind data and capacity factor. Finally, the comparison of the estimated results with the measured data at 10, 30, and 50 m is shown.

AB  - The district heating system in Serbia, with an installed capacity of 6,600 MW, currently supplies 58 towns with thermal energy. As a candidate country for accession to the European Union, Serbia faces the obligation to reduce the level of its greenhouse gas emissions as part of environmental reforms. This paper presents a basic scenario and three alternatives for final energy consumption in the district heating sector for the years 2015, 2020 and 2025. It is suggested that demand for heating will increase 10% up to 2020 and by 15% up to2025, in relation to 2015 levels, while the share of each energy carrier will not change. Changing the structure of energy sources for heat supply assumes a decrease in the share of coal and liquid fuel, and increases in the use of biomass and natural gas. The results obtained were compared to the General Index of Sustainability which is a measure of the complexity of the proposed energy scenario. The paper considers the formation of related energy indicators as quantitative tools for the analysis of changes. It also proposes a methodology for multi-criteria analysis in the sustainability assessment of complex energy systems based on the stochastic evaluation of criteria (sets of indicators and sub-indicators). In this way, the results of the multi-criteria assessment can help in the decision-making process in cases where economic, social and ecological criteria are considered to be influential. © 2018 Serbian Society of Heat Transfer Engineers.

AB  - New Regulations on energy efficiency in buildings in the Republic of Serbia legislate values for the temperature correction factor used to calculate the heat flux to the outdoor environment through construction elements of a certain type. The temperature correction factor is used to correct errors caused by calculation of heat losses based on the design outdoor and indoor temperature difference of building elements adjacent to unheated spaces which are in direct contact with the ground or external environment. Since the temperature correction factor directly influences the calculation of total heat losses and total annual energy demand, it is recommended that the temperature correction factor be determined on the basis of measured values of outdoor and indoor air temperature, or, on the basis of the values obtained by the simulation. This paper presents the results of measurements in the High School of Design, Textile and Management in Belgrade in order to assess energy efficiency and the energy performance of buildings. Data obtained on the basis of measurements, such as indoor and outdoor temperatures, are used for the calculation of the heat transfer coefficient for the building envelope elements as well as to calculate a temperature correction factor for the unheated attic space of the building. This paper also offers a dynamic simulation of the multi-zones building in the TRNSYS environment. The aim was to compare temperature correction factor values obtained from measured temperature values, with those calculated from standard, taken from the Regulation table and produced by simulation. © 2018 Serbian Society of Heat Transfer Engineers.

AB  - In Serbia, a developing country, energy consumption per capita is higher than in most other countries in the region. Implementation of energy management practices is therefore necessary to cut energy consumption and CO2 emissions. This paper gives an insight into how energy management is implemented in Serbian manufacturing (focusing on food processing and manufacturing of non-metallic mineral products, defined as priority industrial sectors). No similar study for Serbian manufacturing has been published. The study was carried out using an on-line questionnaire based on the ISO 50001 requirements. Questions were grouped into 16 categories and presented according to the PDCA (Plan-Do Check-Act) cycle. The propbsed methodology has not been used by other researchers for similar problems. The survey was conducted in 52 organizations and lasted from May to December 2015. We found that the average level of requirements fulfillment in priority industrial sectors in Serbia is 59.05%. Full implementation was found in only 5.8% of participating organizations. Average implementation of the PLAN phase (establishing basics for energy management) is 61.87%, implementation of the DO phase (realization of energy management processes) is 59.98%, implementation of the CHECK phase (monitoring and measurement of energy performance) is 59.61%, and finally, implementation of the ACT phase (review and improvement of energy management) is only 3534%. The study results offer scientific data for improving national policy and education on energy management in Serbia. (C) 2017 Elsevier Ltd. All rights reserved.

AB  - The processes of vaporization in porous structures, working with the excess of liquid are investigated. With regard to the thermal power plants new porous cooling system is proposed and investigated, in which the supply of coolant is conducted by the combined action of gravity and capillary forces. The cooling surface is made of stainless steel, brass, copper, bronze, nickel, alundum, and glass, with wall thickness of 0.0.5.10(-3)-2.10(-3) m. Visualizations of the processes of vaporization were carried out using holographic interferometry with the laser system and high speed camera. The operating conditions of the experiments were: water pressures 0.01-10 MPa, the temperature difference of subcooling 0-20 degrees C, an excess of liquid 1-14 of the steam flow, the heat load 1.10(4)-60.10(4) W/m(2), the temperature difference 1-60 degrees C, and orientation of the system +/- 0-+/- 90 degrees. Studies have revealed three areas of liquid vaporization process (transitional, developed, and crisis). The impact of operating and design parameters on the integrated and thermal hydraulic characteristics was defined. The optimum (minimum) flow rate of cooling fluid and the most effective type of mesh porous structure were also defined.

The operating conditions of the experiments were: water pressures 0.01-10 MPa, the temperature difference of subcooling 0-20 degrees C, an excess of liquid 1-14 of the steam flow, the heat load 1.10(4)-60.10(4) W/m(2), the temperature difference 1-60 degrees C, and orientation of the system +/- 0-+/- 90 degrees. Studies have revealed three areas of liquid vaporization process (transitional, developed, and crisis). The impact of operating and design parameters on the integrated and thermal hydraulic characteristics was defined. The optimum (minimum) flow rate of cooling fluid and the most effective type of mesh porous structure were also defined.",

AB  - The behavior of the mast is non-linear due to its slenderness and compliant guy-support system, having a tendency to lose stability and even crush suddenly. Wind load is one of the main factors affecting the stability of the structure of the mast. Structural assessment of the different mast configurations has been investigated in the past. Furthermore, European standards EN 1993-3-1:2006 and EN 1993-1-6:2007 already provides some guidelines about the basis of structural analysis of masts and towers. This paper presents the results of numerical simulations of a guyed mast exposed to wind action using finite element method. Structural analyses were performed for three different constant wind loads, modal analysis provides the values of natural frequency and mode shapes, while the stability analysis was performed for the first three buckling load factor values. The motivation for this study is to investigate the contribution of finite element method to structural analysis of a lattice structure such as guyed mast as an alternative and/or improvement to the literature and codes.

AB  - The paper presents the results of a technical and economic analysis of three stand-alone hybrid power systems based on renewable energy sources which supply a specific group of low-power consumers. This particular case includes measuring sensors and obstacle lights on a meteorological mast for wind measurements requiring an uninterrupted power supply in cold climate conditions. Although these low-power (100 W) measuring sensors and obstacle lights use little energy, their energy consumption is not the same as the available solar energy obtained on a daily or seasonal basis. In the paper, complementarily of renewable energy sources was analysed, as well as one of short-term lead-acid battery based storage and seasonal, hydrogen-based (electrolyses, H-2 tank, and fuel cells) storage. These relatively complex power systems were proposed earlier for high-power consumers only, while this study specifically highlights the role of the hydrogen system for supplying low-power consumers. The analysis employed a numerical simulation method using the HOMER software tool. The results of the analysis suggest that solar and wind-solar systems, which involve meteorological conditions as referred to in this paper, include a relatively large number of lead acid batteries. Additionally, the analysis suggests that the use of hydrogen power systems for supplying low power-consumers is entirely justifiable, as it significantly reduces the number of batteries (two at minimum in this particular case). It was shown that the increase in costs induced by the hydrogen system is acceptable.

AB  - Manufacturing, which is destined to play the most significant role in the reindustrialization of Serbia is also one of the largest energy consumers and environmental polluters. In accordance with this, a large number of energy and environment management initiatives have been implemented over the years. In developed countries, these initiatives are at an advanced level, but not in Serbia. A group of manufacturers in Serbia has recognized the significance of the environmental initiatives implementation, but the interest in energy management improvement has remained low. Although these initiatives can be used to achieve cost reduction in industry, not all the manufacturing sectors equally value the importance of energy management improvement. Among all the manufacturing sectors, it is necessary to prioritize those with the potentials for energy management improvement, which can be done using different methods. In this paper, the AHP (Analytic Hierarchy Process) method was used to prioritize manufacturing sectors in Serbia in the area of energy management improvement. Using a created AHP questionnaires criteria weights were selected. These questionnaires were completed by the experts from the Serbian Chamber of Commerce and Industry, providing us with the opportunity to evaluate the Serbian manufacturing sectors based on the real life data. The results of the AHP method, which was used as the prioritization instrument, and their analysis are presented in the paper. As a part of a wider study, aimed at the improvement of the energy management in Serbia, the three manufacturing sectors with the highest priority (Manufacture of food products, Manufacture of motor vehicles, trailers and semi-trailers, Manufacture of other non-metallic mineral products) will be analyzed in the future research in terms of energy process flows, energy management system implementation and other relevant issues.

First, the 1 x 19 stainless steel wire strand core was investigated. The numerical analysis was carried out by the finite element method. In this analysis two different types of contacts were investigated: bonded and frictional contact. The strand core was subjected to two different types of axial loading. The obtained results were compared with the solutions calculated from the available literature. Finally, using the advanced modeling techniques, the parametric 3D model of 7 x 19 IWS was also analyzed by using the finite element method, in order to provide a better understanding and, hence, prediction, of the mechanical behavior of the sling wire ropes.

AB  - Guyed masts are used for meteorological measurements, in the telecommunication industry for wireless communication or for power transmission. For a guyed mast, wind load is the main factor affecting the stability of the structure. Determination of drag coefficient for lattice structure has been investigate in past. ESDU 81027 and 81028 and Eurocode 3 Part 3.1 give already some detailed information of the aerodynamic drag coefficient of lattice mast structures with circular members. Only certain types of lattice masts covers literature and codes tend to be conservative due to the necessity of simplicity. But in this study is presented numerical method using Computational Fluid Dynamics (CFD) to determine drag coefficient. The motivation for this study to investigate what CFD can offer or contribute to determine the aerodynamic drag forces of lattice mast structures as a supplement or even alternative to literature and codes. This would be in particular of interest for design engineers in the field of mast structures. Three-dimensional numerical simulations of one segment of a mast exposed to a wind action with three models of turbulence are performed. Three models of turbulence: standard k-epsilon model, RNG k-epsilon model and Reynolds stress model were used and compared with available experimental results. Drag coefficient was calculated based on integration surface pressure distribution, flow field and a reference area. Modeling was performed for four wind velocities, 10 m/s, 20 m/s, 30 m/s and 40 m/s. Reynolds number for those velocities corresponds to turbulence flow. Direction of inlet velocity is also variable, e.g. there are two angles of attack. (C) 2014 Elsevier Ltd. All rights reserved.

AB  - As a non-Annex I Party to the United Nations Framework Convention on Climate Change and Kyoto Protocol signatory, the Republic of Serbia has committed to develop GHG (Greenhouse Gases) emission inventory and prepare comprehensive program of mitigation measures at national level. The paper presents results of 2000-2008 GHG emission inventory assembled for PDH (Public District Heating) sub-sector in accordance with revised IPCC (Intergovernmental Panel on Climate Change) Tier 1 methodology. Evaluation of proposed mitigation measures was performed based on 2012 and 2015 GHG emission projections, obtained for basic and four alternative scenarios, all characterized by the same energy demand but with different fuel mix used. The first alternative scenario addresses GHG emissions in case that solid fuel is substituted by natural gas. The second alternative scenario represents a sub-scenario of the first alternative scenario, with additional substitution of liquid fuel with locally available biomass.

abstract = "As a non-Annex I Party to the United Nations Framework Convention on Climate Change and Kyoto Protocol signatory, the Republic of Serbia has committed to develop GHG (Greenhouse Gases) emission inventory and prepare comprehensive program of mitigation measures at national level. The paper presents results of 2000-2008 GHG emission inventory assembled for PDH (Public District Heating) sub-sector in accordance with revised IPCC (Intergovernmental Panel on Climate Change) Tier 1 methodology. Evaluation of proposed mitigation measures was performed based on 2012 and 2015 GHG emission projections, obtained for basic and four alternative scenarios, all characterized by the same energy demand but with different fuel mix used. The first alternative scenario addresses GHG emissions in case that solid fuel is substituted by natural gas. The second alternative scenario represents a sub-scenario of the first alternative scenario, with additional substitution of liquid fuel with locally available biomass. Third alternative scenario addresses emissions resulting from complete fuel switch from natural gas to liquid fuel oil, while the final alternative scenario considers the case when natural gas is the only energy resource used. GHG emission trends in the period until 2015, examined in case of previously mentioned basic and four alternative scenarios, point out to the positive impact of fuel switch on GHG emission reduction and pathways for future implementation of proposed mitigation measures.

AB  - This paper presents the mathematical procedure for the determination of overall sustainability index of nine options for the agglomeration of economic, environmental and social indicators. Eleven sub-indicators were selected and calculated for all chosen options. In accordance to final energy consumption (for space heating, hot water production, cooking and the household electrical appliances) the selection, defining and determining the economic, social and environmental indicators was developed. It was done for all chosen options selected by qualitative characterization of residential objects in accordance with construction period, type of heating system and type of object (buildings or family houses). Investigation of the influence of non-linear normalization on the sub-indicators agglomeration was the aim of this paper. Normalized sub-indicators are obtained by selection of the appropriate linear (theta = 1) or non-linear function (theta not equal 1). Sustainability index and its standard deviation were calculated for different value of the parameter theta and each option in six different cases. The functional dependence between the sustainability index and the associated standard deviation of the theta parameter (characterizing the way of normalization) was obtained. (C) 2012 Elsevier B.V.

AB  - The revised Intergovernmental Panel on Climate Change guidelines for national greenhouse gas inventories recommends that more comprehensive and thus more reliable characteristics of the local fossil fuels should be used for the national greenhouse gas inventory calculations. This paper deal with the carbon emission characteristics of low-calorific lignite recovered from the Kolubara open-pit mine. The samples of coal were carefully selected in order to cover the net calorific value, ash and water content of the broad spectrum of the quality of the raw lignite supplied to the Serbian thermal power plants. Correlation analysis of the laboratory analysis data gave a linear dependency of the net calorific value on the combustible content in the coal samples. Also, linear correlation between the carbon content and the net calorific value was found. The regression analysis of experimentally determined coal characteristics implies that the carbon emission factor is dependent on the net calorific value. For the subset of raw lignite samples with the net calorific value Q(d)(r) = 6-10 MJ/kg, that is most representative for current and near future use for power generation in Serbian thermal power plants, the linear dependency CEFr (tC/TJ) = 34.407 - 0.5891.Q(d)(r) MJ/kg was proposed. Regarding the net calorific ranges of samples examined, the raw Kolubara lignite carbon emission factor is considerably higher than those recommended by Intergovernmental Panel on Climate Change Tier 1 method of 27.6 tC/TJ.

AB  - This paper deals with the numerical simulation of air flow around the arrays of flat plate collectors and determination of the flow field, which should provide a basis for estimating a convective heat losses, a parameter which influences their working characteristics. Heat losses are the result of the reflection on the glass, conductive losses at the collectors absorber plate, radiation of the absorber plate and convective losses on the glass. Wind velocity in the vicinity of the absorber plate depends on its position in the arrays of collectors. Results obtained in the numerical simulation of flow around collectors were used as boundary conditions in modeling of thermal-hydraulic processes inside the solar collector. A method for coupling thermal-hydraulic processes inside the collector with heat transfer from plate to tube bundle was developed, in order to find out the distribution of the temperature of the absorber plate and the efficiency of the flat plate collectors. Analyses of flow around arrays of collectors are preformed with RNG k-epsilon model. Three values for free-stream velocity were analysed, i.e. 1 m/s, 5 m/s, and 10 m/s, as well as two values for the angle between the ground and the collector (20 degrees and 40 degrees). Heat transfer coefficient was determined from the theory of boundary layer. Heat transfer inside the plate cavity was analyzed assuming constant intensity of radiation.

AB  - Two possible substitutions for fossil fuel used in heat production are biomass and solar energy. This paper presents an evaluation of various energy sources for hot water production in a heating plant. The heating plant was situated in one of the largest municipalities in the city of Belgrade, Serbia. It produces and delivers domestic hot water and energy for heating to approximately 17,000 households. It is possible to use of using renewable energy instead of fossil fuel for producing the thermal energy for the supply of domestic hot water. Hence, in this paper, an evaluation of the sustainability of different energy options for obtaining thermal energy was considered: 1) from gas combustion: 2) from gas combustion and solar collection 3) from biomass combustion 4) from gas and biomass combustion, and 5) from gas and biomass combustion and solar collection. To compare the different energy systems, the method of multi-criteria analysis was utilised. This method integrates various multi-dimensional criteria and provides an efficient method of estimating the sustainability of complex systems. The obtained results were compared by the General Index of Sustainability which is a measure of the complexity of a system. A basic set of energy indicators that relate to different aspects of sustainable development was defined. In this way, the results in the assessment of sustainability of energy options do not depend on the various analysts in decision making. (C) 2010 Elsevier Ltd. All rights reserved.

AB  - Assessing the sustainability of urban energy systems and forecasting their development are important topics that have been the focus of recent research. In this paper, an approach for the measurement the sustainability of an urban energy system is introduced. The approach is based on prediction of the future energy needs within the consuming sectors of a city by specification of energy system development scenarios and validation of the scenarios by a multi-criteria decision method. Prediction of energy needs for the area of the city using the simulation model, model for analysis of the energy demands (MAED) is done. Finish the last level of aggregation, using the method of multi-criteria analysis, is getting the General Index of Sustainability (GIS), which shows a measure of the validity or viability, or quality of the investigated scenarios. In this way, the mathematical and graphical made a synthesis of all the indicators that are relevant to sustainable development. The accuracy in determining the mean of the GIS is checked by calculating the standard deviation. Also, a measure of reliability of the preference when watching a few consecutive scenarios was performed. The defined scenarios take into account the utilization of different energy sources, the exploitation of existing energy plants and infrastructure, and the building of new plants. The sustainability criteria are described by a unique set of economic, social and ecological indicators. The new approach was used to forecast the development of sustainable energy system in Belgrade, Serbia. (C) 2010 Elsevier Ltd. All rights reserved.

AB  - The main objective of this paper is to evaluate energy and environmental benefits of the large-scale solar heating system connection with district heating system. The assessment of fossil fuels substitution by the solar energy for the hot water production for domestic use, during the summer period, is done. Hot water for district heating and domestic use is produced in heating plant Cerak placed in the suburb of Belgrade. The existing production and distribution system are based on fossil fuel energy, mainly on the natural gas. in the first phase of the project plan was to install about 10,000 m(2) of solar collectors to substitute nearly 25% of natural gas consumption. During the summer period, the saving of natural gas calculated for presented system is approximately 430,000 m(3) and in this way 900 t of the CO(2) emissions would be reduced.

For the most part such areas are under special care of the state (i.e. underdeveloped, devastated by war, depopulated), on islands or in mountainous regions. Since the decentralized energy generation covers a broad range of technologies, including many renewable energy technologies that provide small-scale power at sites close to the users, such concept could be of interest for these locations. This paper identfies the areas in Western Balkans where such systems could be applied Consideration is given to geographical locations as well as possible applications. Wind hydro, solar photovoltaic, and biomass conversion systems were taken into consideration. Since the renewable energy sources data for Western Balkans region are rather scarce, the intention was to give a survey of the present situation and an estimate of future polential for decentralized energy generation based on renewable energy sources. The decentralized energy generation based on renewable energy sources in Western Balkans will find its niche easier for the users that will produce electricity for their own needs and for the users located in remote rural areas (off-grid applications).

A mathematical model for prediction of velocity, temperature and concentration fields of axisymmetric free premixed turbulent flame is presented in this paper. A second-order closure for turbulent reacting flows is used. Special attentions is paid to model behavior with the respect to the prediction correlation coefficients of turbulent diffusion of the scalar components. Conditional and unconditional statistics of the LDA signals were performed using jet and/or air seed. Compared to commonly used unconditional statistics, conditional statistics of velocity fluctuations can give us more data about intensity of turbulent mixing in the flame. (c) 2006 Elsevier Ltd.
