AB  - In this paper, some results concerning the evolution of the fluid flow pattern and flame propagation of various fuels in a particular combustion chamber with four tilted valves were elucidated. Flame propagation was represented by the evolution of spatial distribution of temperature in various cutplanes within combustion chamber. Flame front location was determined in the zones with maximum temperature gradient. All results were obtained by dint of multidimensional modeling of reactive flows in arbitrary geometry of IC engine combustion chamber with moving boundaries. The above mentioned results were analysed and presented for two different hydrocarbon fuels such as gasoline and methane and one alchocol based fuel such as ethanol. The results for all three fules considered were obtained by dint of eddy-viscosity model i.e. with standard k-ε model of turbulence. The interplay between fluid flow pattern and flame propagation is entirely invariant as regards fuel variation indicating that flame propagation through unburnet mixture considered fuels is not chemically controlled but controlled by dint of turbulent diffusion.

AB  - The anticorrosive properties of single and sandwich layers obtained by pulsed laser deposition (PLD) of the pseudo-binary oxide ZnTa2O6 and zinc meso-tetra(4-pyridyl)porphyrin (ZnTPyP) on steel were investigated. Intercalated thin layers made by PLD technique from the pseudo-binary oxide ZnTa2O6 and zinc meso-tetra(4-pyridyl)porphyrin (ZnTPyP) are expected to self-assemble into ordered nanoparticles and to exhibit uniformity and adherence, offering novel anticorrosive properties. The corrosion tests were performed in solution 0.1 mol l-1 NaCl. The best corrosion resistance was exhibited by the steel electrode modified with ZnTPyP/ZnTa2O6 deposited layers, i.e. 66.64% inhibition efficiency. © 2019 IOP Publishing Ltd.

AB  - Hydrothermally obtained Mg3Ta208 pseudo-binary nanomaterial from MgO and Ta2O5 (3:1) precursors was deposited using the pulsed laser deposition (PLD) technique on carbon steel disks. The PLD main processes parameters, i.e. the pulse energy and the deposition time were varied in order to determine the combination that ensures the best corrosion inhibition. Morphological investigations were carried out (scanning electron microscopy and atomic force microscopy). The anticorrosive properties of the deposited layers were studied in 0.3 M NaCI saline solution. The best anticorrosive protection was observed in the case of the deposited layers on carbon steel disk using the lower energy, i.e. 10mJ for a deposition time of 60s, i.e. 61.94 % inhibition efficiency.

AB  - The Pressure Equipment Directive (PED) and Regulations on Technical Requirements for Designing, Manufacturing and Conformity Assessment of Pressure Equipment bring a number of changes to the design of pressure equipment in relation to the Technical Regulations for Stable Pressure Vessels, 1983. Among the most important changes are the essential safety requirements for pressure equipment. The changes in the formula, for all materials, for calculating the allowable stresses, as well as the change in the value of the test pressure, the new Regulations use the 1.0% proof strength as the relevant value for calculating the permissible membrane stress and thickness of pressure equipment walls. In this paper, the differences in the allowable stresses, the required wall thicknesses, and the approximate savings in the material in the case of a milk reservoir, calculated according to the requirements of the Directive and the new Regulations on one hand, and the old Regulations on the other, are presented. © 2018 The Author.
