## Abstract The flow field around a circular cylinder elastically suspended with a cantileverβtype plate spring in the jet impingement region was visualized to investigate the mechanism of the impingement heat transfer. The impingement distance __H__ was kept constant at 3 or 5 times as large as th

## Abstract An experimental and numerical simulation study of heat transfer due to a confined impinging circular jet is presented. In this research, a stainless steel foil heated disk was used as the heat transfer surface of a simulated chip, and the thermocouples were mounted symmetrically along t
Several CFD calculations have been performed in order to assess the ability of common __kβΟ΅__ turbulence models to predict heat transfer in impingingβjet flow. One focus is on the influence of the wall on the flow, calculated either by applying a logarithmic wall function or by resolving the flow do
