AB  - This work presents a data reduction procedure of the direct pulse heating technique with both contact and radiance temperature measurements. The technique is applied for the measurement of thermophysical properties of electroconductive solids over a wide temperature range, i.e., from room temperature up to about 2300°C. Absolute and radiance temperatures of a tested material are measured by thermocouple and radiation thermometer, respectively and these and other experimental data are then reduced to the values of specific heat, specific electrical resistivity, hemispherical total emissivity and normal spectral emissivity of the tested material. The related data reduction and corresponding uncertainty assessment for each property is described in detail. An example of uncertainty assessment is given for the recent measurement of specific heat, specific electrical resistivity, hemispherical total emissivity and normal spectral emissivity at 900 nm of molybdenum alloy TZM specimens.

AB  - As the global population becomes more concentrated in urban environments, higher numbers of people will be exposed to urban air pollution. The environmental and human health benefits of green roofs are widely recognized. The aim of this paper is to promote green roofs as an effective passive technique for pollution mitigation and adaptation to climate change. During the heating season, the ambient concentrations of PM1, PM2.5, and PM10 were measured above a green roof and a reference roof on a school building, located in New Belgrade, the second-most populous municipality and business center of Serbia’s largest city. The percent reduction of PM10, PM2.5 and PM1, in January 2020, above the green roof compared to the reference roof was 7%, 16.6%, and 17.6%, respectively. The results show that lightweight green roof improve air quality in terms of PM concentrations for all months considered. In this paper, correlation analysis and the use of Pearson’s coefficient were used in the process of analysis to determine the relationship between PM10, PM2.5, PM1, and ambient parameters: relative humidity, ambient temperature, and wind speed. It was found that the statistical correlation expressed by the Pearson coefficient between all PM particles and wind speed was statistically significant in all observed months except September. Also, the degree of significance of the correlation between PM particles and humidity and temperature of ambient air varies by month.

AB  - An inter-laboratory comparison has been performed between seven participants on thermal diffusivity measurements by the laser flash method in the temperature range from 23 °C to 3000 °C. The main objective was to assess the variability and coherency of thermal diffusivity measurements performed at ultra-high temperatures at the European level. Three refractory materials (molybdenum, tungsten and isotropic graphite IG210) were selected for this inter-laboratory comparison, due to their high melting point. The disk-shaped specimens needed were machined from the same blocks of materials in order to reduce any potential scattering of results between participants due to inhomogeneity effects. The homogeneity of the sets of specimens was studied by the pilot laboratory (LNE) before launching the comparison process. Thermal diffusivity measurements were then carried out by the seven participants on the three materials during two successive thermal cycles up to the maximum temperatures that can be reached by the devices used. The analysis of results showed a good agreement between the participants for temperatures above 400 °C, with relative deviations within the uncertainties of measurement and lower than ± 4 % for molybdenum, ± 5 % for isotropic graphite and ± 9 % for tungsten. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Green roof systems have become an important part in creating sustainable cities. They can provide a wide range of economic, environmental, and social benefits. The goal of this research was to quantify the thermal performance improvements from a green roof with mineral wool substrate installed on a school building in a humid subtropical climate. In-situ measurements during a summer period included heat fluxes through the green and reference roof, vertical temperature profile through both roofs, the local air temperature above roofs, and local meteorological parameters. Furthermore, the summer thermal performance of green and reference roof and the green roof cooling effect were evaluated concerning meteorological parameters using the Pearson correlation analysis. The results indicate that the green roof layers have improved thermal performance of the roof with respect to reduced conductive heat flow by 57% and delayed heat transfer. The maximum and averaged reference roof to green roof outdoor surface temperature difference was 27.5 °C and 5.5 °C, respectively. It was found that ambient temperature and relative humidity have a dominant role on the thermal performance of the green and reference roof, while solar radiation and ambient temperature present the key meteorological determinants of the green roof cooling effect.

AB  - Institute VINCA, respectively French National Metrology Institute and Serbian Designated Institute for thermal properties metrology, on thermal conductivity measurements by the guarded hot plate method. The main objective was to validate the measurement capabilities of VINCA in terms of thermal conductivity in the temperature range from 10 degrees C to 50 degrees C by using the facility improved in the frame of the European project Eura-Thermal. The measurements were carried out on expanded polystyrene boards using guarded hot plate apparatuses (two-specimen GHP apparatuses) in accordance with the international standard ISO 8302. The measurement programme was defined taking into account the major characteristics of the guarded hot plate apparatuses used, such as specimen dimensions and temperature and thermal conductivity ranges. Specimens were machined by LNE from a same batch for both participants. Prior to the measurements, the homogeneity of the set of specimens, as well as the influence of a variation of density of the expanded polystyrene on the thermal conductivity measurements were studied by VINCA. The obtained results showed good agreement between the two laboratories, with relative deviations within the uncertainties of measurement. Also, the results validated the level of uncertainty assessed by VINCA for its thermal conductivity measurements to around 2.5 % (with a coverage factor of 2) between 10 degrees C and 50 degrees C.

Топлотна проводност се, као једна од најзначајнијих термофизичких величина чврстих материјала, мери различитим експерименталним методама. Метода која код слабо проводних материјала може обезбедити резултате са најмањом могућом мерном несигурношћу је метода заштићене топле плоче и она се као референтна користи у свим најзначајнијим националним метролошким лабораторијама у свету. Експериментална поставка којом се примењује ова метода је установљена у Институту ВИНЧА још 60-их година прошлог века и била је функционална до средине 80-их. Топлотна проводност термоизолационих материјала се у том периоду мерила са релативном мерном несигурношћу од 3 % до 10 %. У складу са убрзаним развојем МЛТВ почетком овог века, као и њеним каснијим признавањем као именоване националне лабораторије за термофизичке величине, приступило се ревитализацији експерименталне поставке и унапређењу поступка одређивања топлотне проводности. У оквиру рада на овој дисертацији је унапређена како сложена мерна апаратура кроз моделовање, израду и тестирање нових елемената и система, тако и калибрациони и мерни поступак и начин обраде мерних сигнала. Као резултат широког унапређења, данас се у Институту ВИНЧА топлотна проводност термоизолационих чврстих материјала може мерити са високом тачношћу и прецизношћу, тј. малом релативном мерном несигурношћу која достиже ниво од 2 %. Тим резултатом, који је потврђен преко међународног међулабораторијског поређења извршеног у оквиру Eura-Thermal пројекта, Метролошка лабораторија за температуру и термофизичке величине Института ВИНЧА се сврстала у ред значајних светских лабораторија те врсте.
AB  - This PhD thesis implies research on improving the thermal conductivity measurement of thermal insulations in the Metrological Laboratory for Temperature and Thermophysical Properties (MLTV) of the Institute of Nuclear Sciences VINČA. Thermal conductivity, as one of the most important thermophysical properties of solid materials, is measured by various experimental methods. A method that may provide results with a lowest possible measurement uncertainty for poorly conductive materials is the guarded hot plate method and it is used as a reference technique in all most important national metrology laboratories in the world. A related experimental setup was established at the Institute VINČA in the 1960s and was functional until the mid-80s. Thermal conductivity of thermal insulation materials was measured in this period with a relative uncertainty of 3 % to 10 %. In accordance with a fast development of MLTV at the beginning of this century, as well as its subsequent recognition as the designated laboratory for thermophysical properties, a revitalization of the experimental setup and an improvement of the corresponding measurement process began. Within the scope of this dissertation, the measurement apparatus was improved through modelling, designing and testing of new elements and systems, as well as through new calibration, measuring and data reduction procedures. As a result of these improvements, today, the Institute VINČA is capable to measure the thermal conductivity of insulation materials with a high accuracy and precision, i.e. with small relative uncertainties down to a level of 2 %. With this result, which was confirmed through an international inter-laboratory comparison performed within the framework of the Eura-Thermal project, the MLTV of the Institute VINČA has been ranked among the world's leading laboratories of this kind.

Inside a controllable temperature and humidity environment, supplied by a mixed-flow humidity generator, measurements of hygrometers under calibration are compared with those of calibrated reference instruments. A traceability chain from temperature to reference relative humidity and next to the hygrometers under calibrations is provided by using a chilled-mirror dew-point temperature system and precise relative humidity probes. Corresponding calibration uncertainties are analyzed, particularly those associated to the temperature uniformity of controlled calibration environment. Two examples of relative humidity calibration with dew-point and relative humidity reference measurements in the range from 15 to 75% of RH and 5 degrees C to 45 degrees C are presented and discussed.

Metoda se primenjuje u Labaratoriji za termotehniku i energetiku Instituta za nuklearne nauke “Vinča” od kraja 60-ih godina i daje dobre i pouzdane rezultate u opsegu od 10 do 200 °C. Tokom poslednje godine metoda je podvrgnuta reviziji i unapređena izradom programa za automatizovanu akviziciju, prikaz i obradu podataka pod kontrolom računara. Primena unapređenja ilustrovana je eksperimentima na referentnim uzorcima od Ilford stakla. Nekoliko uzastopnih eksperimenata sa različitim kontaktnim medijumom na površinama uzorka ispitan je uticaj kontaktnog otpora na rezultat merenja.

abstract = "U radu je opisana aparatura za merenje toplotne provodnosti slaboprovodnih materijala, u koje spadaju stakla, plastike, gume, keramike i sl. Metoda se primenjuje u Labaratoriji za termotehniku i energetiku Instituta za nuklearne nauke “Vinča” od kraja 60-ih godina i daje dobre i pouzdane rezultate u opsegu od 10 do 200 °C. Tokom poslednje godine metoda je podvrgnuta reviziji i unapređena izradom programa za automatizovanu akviziciju, prikaz i obradu podataka pod kontrolom računara. Primena unapređenja ilustrovana je eksperimentima na referentnim uzorcima od Ilford stakla. Nekoliko uzastopnih eksperimenata sa različitim kontaktnim medijumom na površinama uzorka ispitan je uticaj kontaktnog otpora na rezultat merenja.",
