Abstract

Mixed natural/forced convective heat transfer in a channel with heating elements is reported. Three microelectronic chps provided the heating surfaces. An experimental study was performed to determine the influence of the Reynolds number and Grashof number on the Nusselt number. Real-time holographic interferometry with an optical crystal as the storage medium was used to visualize heat transfer from microelectronic chips. The results show that the influence of natural convection is usually negligible, even for small Reynolds numbers
