Using single/multiple layers of highly conductive metallic wire mesh screen bonded to a plain heat transfer base surface, the two-phase heat transfer performance of a microjet impinging onto a porous coated copper surface was studied. Experiments were conducted at three different flow rates of water under atmospheric pressure. For comparison, experiments of jet impinging on a plain copper surfa...

The Study of heat transfer augmentation in micro scale and electronic packaging systems are some of the paramount areas of the impending universe. In such systems the cooling of the heat sinks are generally achieved through the impingement of air jet. Assuming the air jet to be continues & incompressible fluid, the heat dissipation rate over the target surface seems to either uniform or well ch...

Various types of impinging jet flows are analytically modeled using inviscid free Gaussian jet solutions superimposed with experimentally fitted boundary layer models. Improved (more robust) and simplified solutions to existing models are defined. Velocity profiles, surface pressure distributions, and streamline plots are calculated for circular, plane, and annular impinging jets. The models sh...
