Numerical Simulation and Experiment of Supersonic Jet Impingement on a Plate.

Numerical Simulation of Mixing Enhancement in a Hot Supersonic Jet

Experimental observations show that the presence of small tabs on the edge of a hot, compressible jet exiting into a slower moving, colder ambient ow can increase the rate of spreading of the jet. This suggests that the rate of mixing of the jet and the ambient uid is also increased. In order to elucidate the physical mechanism responsible for the increased spreading rate a set of calculations ...

Numerical Simulation of Minimum Distance Jet Impingement Heat Transfer

Impinging jets are used in various in cooling and drying technique. The current research the means of improving the heat transfer for con minimum distance of the nozzle to the impingem impingement heat transfer is described using nume a wide range of parameters for an array of p parameters include varying jet flow speed, width o of nozzle, angle of the jet flow, velocity and impingement surface...

Highly rarefied two-dimensional jet impingement on a flat plate

In this paper, we investigate highly rarefied jet gas flows out of a two-dimensional slit that impinges on a flat plate which is set vertically to the plume flow direction. The plate is assumed to be completely diffusive and the gaseous plume flow out of the slit is modeled with a Maxwellian distribution function which is characterized with known number density, nonzero exit velocity, and tempe...

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...
