Pulse Mitigation and Heat Transfer Enhancement Techniques. Volume 2. Effect of Surface Wettability and Roughness in Evaporative Spray Cooling

Abstract

In the spray cooling of a heat surface, variations in the surface contact angle cause a change in nucleation characteristics and thereby influence the heat transfer process. The surface roughness variations affect the thickness of the liquid film formed by the spray; this has a profound effect on the heat transfer from the surface. The effect of these two parameters is studied experimentally under different spray conditions involving an air atomizing nozzle.
