(VINCA INST NUCLEAR SCI, 2020)
In this study, performance of two different environmentally friendly systems with natural refrigerant solutions, R744 transcritical booster system with ejector and a R290/R744 cascade system are examined theoretically by ...
Computational investigation of the velocity and temperature fields in corrugated heat exchanger channels using RANS based turbulence models with experimental validation
(INDERSCIENCE ENTERPRISES LTD, 2018)
The characteristics of convective heat transfer and friction factor for periodic corrugated channels are investigated numerically. In the numerical study, the finite volume method (FVM) is used. Three different Reynolds ...
Characterisation and comparison of disc brake pads of heavy vehicles by experimental methods
(INDERSCIENCE ENTERPRISES LTD, 2019)
In this study, characteristics of disc brake pads of heavy vehicles produced by three different manufacturers were compared experimentally. The former pad is the original (OEM), the latter pad is the subsidiary industrial ...
EXPERIMENTAL AND NUMERICAL ANALYSIS OF FLOW OVER A PICKUP TRUCK
(Begell House Inc., 2021)
The drag forces and the overall drag coefficient of a typical pickup truck are investigated experimentally and the 3D numerical analysis is performed. A detailed 1/4-scale model is constructed and experiments are performed ...
Friction and wear properties of heavy load truck composite brake linings
(Walter de Gruyter GmbH, 2021)
Materials for friction used in brakes should fulfill many requirements, such as stable friction performance in all conditions, lower change in the friction coefficient, high wear resistance and low wear rate. In this study, ...
