Thermodynamic based environmental and sustainability assessments of gas flow in a curved annular channel
(Pergamon-Elsevier Science Ltd, 2020)
The main objective of this research paper is to perform a parametric comparison of gas flow (air and hydrogen) through a curved channel in terms of thermodynamic based environmental and sustainability analysis. For this ...
Effect of laminar airflow unit diffuser size on pathogen particle distribution in an operating room
(Taylor & Francis Inc, 2020)
Operating room ventilation is quite important to protect patients from infection risk inside a surgical field. the laminar flow units (LAF) used in these applications contribute to removal of pathogen particles from the ...
Numerical analysis of entropy generation in a square cavity filled with boron-water nanofluid
(Springer Heidelberg, 2020)
The entropy generation and natural convection in a square cavity filled with boron-water nanofluid is numerically investigated under the influence of different nanoparticle volume fractions and buoyancy forces when heated ...
Flow boiling characteristics in a novel minichannel with a step on each corner
(Taylor & Francis Inc, 2020)
In the present study, flow boiling in a single minichannel with a longitudinal step on its each corner is studied experimentally. Bubble/flow dynamics, and thus, underlying physical phenomenon is investigated through ...
The effect of solid boriding time on the structure, hardness and corrosion properties of AISI 5140 steel
(Maik Nauka/Interperiodica/Springer, 2020)
In this study, AISI 5140 steel samples were borided in an electrical furnace at a temperature of 950 degrees C for 4, 6 and 8 h. Structural examinations, hardness measurement and corrosion tests were performed to determine ...
Microstructural, mechanical and tribological properties of ultrafine-grained Cu-Cr-Zr alloy processed by high pressure torsion
(Elsevier Science Sa, 2020)
The effect of temperature on tribological properties of coarse grained (CG) and ultrafine-grained (UFG) Cu-Cr-Zr alloy processed via high pressure torsion (HPT) was investigated. Dominant wear mechanism depends on both ...
Prediction of two-phase heat transfer coefficient of flow boiling in minichannels
(Taylor & Francis Inc, 2020)
The present study mainly concentrates on the prediction of two-phase heat transfer coefficient for saturated flow boiling conditions in minichannels. the experimental database has been generated through systematic experiments ...
Experimental and statistical analysis of the effects of punching and laser cutting methods on induction motor efficiency and total magnetic losses in silicon lamination sheets
(Elsevier, 2023)
In this study, M400-50A electrical steel laminations (ESLs) used in electrical machines were cut with punching and laser methods and the effect of these cutting methods on the efficiency and total losses of induction motors ...
Thermal insulation and mechanical properties of a specially improved insulation plaster under freezing-thawing and high-temperature conditions
(Oxford University Press, 2023)
In this study, the effects of heat preservation and the resistance to environmental conditions of ready-made insulating sludge used in the interior and exterior facades of the buildings were investigated. The insulation ...
Thermodynamic performance analysis of a low-cost, recycled and energy-efficient solar air heater with waste beverage cans: an experimental research
(Springer, 2023)
Solar air heaters are at the centre of interest owing to their widespread use for various purposes. In the study, thermal performance analysis of a solar air heater that can be easily produced from daily waste materials ...
