Abstract:

A theoretical study is carried out to predict the thermal behavior of a solid surface subjected to multi-droplet evaporative cooling. A single-droplet numerical code, which has been previously presented and validated, is used here to gain insight into the behavior of a surface subjected to dropwise evaporative cooling. On the basis of the single-droplet results, a generalized model is presented and a novel numerical code is formulated, which analyzes the effects of a multi-droplet evaporative transient on a low thermal conductivity solid surface. The main parameters that characterize the evaporative transient behavior are identified. Some numerical results obtained with this new model are presented and discussed.
