Processing of T6 heat-treated Al-12Si-0.6Mg alloy
(Taylor & Francis Inc, 2020)
In this study, ternary Al-12Si-0.6Mg material was manufactured by gravity die casting method in induction melting furnace. Microstructure images of alloy were taken on optical microscope after T6 heat treatment. Hardness, ...
Numerical performance modelling of solar chimney power plants: Influence of chimney height for a pilot plant in Manzanares, Spain
(Elsevier, 2020)
3D axisymmetric CFD model is developed for a solar chimney power plant (SCPP) in Manzanares, Spain, and potential impacts of chimney height (H) on main performance parameters are comprehensively analysed. Mesh-independent ...
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 ...
A review on environmental impacts from aviation sector in terms of life cycle assessment
(Inderscience Enterprises Ltd, 2020)
The main objective of this paper is, in terms of LCA (life cycle assessment), to compile and discuss, environmental impacts of aircraft, gas turbine engine and components, and maintenance process and operations in the ...
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 ...
