NUMERICAL STUDY OF COOLING BY TANGENTIAL SYNTHETIC JET

Numerical Investigations of Piston Cooling Using Oil Jet

Thermal loading o f diesel engine pistons has increased dramatically in recent years due to applications of various technologies to meet low emission and high power requirements. Control of piston temperatures by cooling of these pistons has become one of the determining factors in a successful engine design. The pistons are cooled by oil jets fired at the underside from the crankcase. Any unde...

Numerical and Experimental Investigations on Jet Impingement Cooling

Effective cooling of electronic equipment has emerged as a challenging and constraining problem of the new century. In the present work the feasibility and effectiveness of jet impingement cooling on electronics were investigated numerically and experimentally. Studies have been conducted to see the effect of the geometrical parameters such as jet diameter (D), jet to target spacing (Z) and rat...

Study of Three-dimensional Synthetic Jet Flowfields Using Direct Numerical Simulation

The formation and evolution of 3D synthetic jets is examined using direct numerical simulations. The primary focus of the current study is on examining the formation of 3D synthetic jets and the effect of changes in the jet aspect-ratio on the flow produced by the jet. Jets in quiescent and cross-flow cases are investigated. The study compares the vortex dynamics, velocity profiles and the othe...
