Abstract:

An experimental investigation was carried out to study the effect of multiple jet impingement on a simulated electronic component using air as working fluid. It consists of an electrically heated test plate of size 2cmX2cm area. Heat flux is varied from 25
to 250W/cm2 was dissipated using 0.25 and Tests were conducted by changing the [i] heat flux, [ii] flow rate, [iii] distance between the test surface and jet exit. It was found that heat flux, jet diameter and Reynolds number are important factors in determining the heat transfer. The effects of distance between test surface and jet exit [Z], and positioning of the jets (Vertical/horizontal) were insignificant.

Keywords:
