Experimental Study of Multiple Droplet Evaporative Cooling

摘要

The purpose of the experimental study was to quantify the transient evaporativecooling of a radiantly heated, low thermal conductivity material subject to a random impingement of water droplets. Specifically, the transient behavior and spatial distribution of the surface temperature were investigated over a range of initial surface temperatures and impinging mass fluxes. Additionally, it was desired to draw some conclusions about the important parameters in the evaporative cooling phenomenon, and about evaporative cooling generally. A concurrent goal of the research was to continue development of the infrared thermography and digital image analysis techniques and equipment employed in the data acquisition system.
