Abstract: This paper reports an investigation of the effects of surface conditions of forwardfacing steps (FFS) on turbulent flows. Three surface conditions including one smooth step and two rough step surfaces created using sandpapers ...

Abstract: This paper reports an experimental study on the effects of adverse pressure gradient (APG) and Reynolds number on turbulent flows over a forward facing step (FFS) by employing three APGs and three Reynolds numbers. A ...

Abstract: In this study, a thermodynamic analysis of a hydraulic braking energy recovery system used in vehicles is performed for newly developed systems. The present system is related to the field of energy efficiency in vehicles. ...

Abstract: This study reports the results of turbulent flows forward facing steps (FFS) in pressure gradients using a particle image velocimetry (PIV) technique to obtain data up to 68 step heights downstream. The contours of two-point ...

Abstract: In this paper, the problem of air cooling and temperature nonuniformity at the cell and pack level is addressed. Passive techniques are developed by integrating jet inlets and vortex generators (VGs) in a simple battery ...

Abstract: Lithium-ion (Li-ion) batteries have been considered the most promising power source for road transportation. However, the performance and lifespan of Li-ion batteries are strongly dependent on the working temperature. The ...

Abstract: Three-dimensional turbulent wall jet was investigated using a particle image velocimetry technique. Three Reynolds numbers based on the jet exit velocity and diameter of 5000, 10,000, and 20,000 ...

Abstract: Three-dimensional turbulent offset jets were investigated using a particle image velocimetry technique. Three jet exit Reynolds numbers, Rej = 5000, 10,000, and 20,000, and four offset heights, ...

Abstract: This paper reports a study of the turbulent wake of two-dimensional rectangular cylinders in an open channel. Three cylinders with different aspect ratios were mounted vertically at the midspan of an open channel and ...

Abstract: In this paper, a multigeneration system is proposed, which utilizes geothermal energy and a lithium-bromide absorption cooling cycle. The proposed system is capable of providing electricity, heating, cooling, and domestic ...
