LIQUID JET IMPINGEMENT

ABSTRACT

Liquid jet impingement is appealing because the liquid supply arrangement is relatively simple and low thermal resistances can be routinely achieved. When operated at high velocity, jets can remove fluxes several times that at the surface of the sun. This article reviews heat transfer and flow phenomena during unsubmerged liquid jet impingement and provides correlations for calculating the heat transfer coefficients. Convective transport without phase change is covered in detail. Results for the stagnation zone are given first, followed by those for the regions downstream. Both axisymmetric and planar jets are considered. The splattering that accompanies turbulent jet impingement is described, and other aspects of liquid jet impingement cooling are surveyed briefly.
