Abstract:

A numerical code for the prediction of evaporative cooling of solid surfaces induced by a gently deposited water droplet is presented. The code is based upon a solid-liquid coupled model which predicts the droplet evaporation and the solid surface cooling for materials with thermal conductivity spanning over more than two orders of magnitude. The numerical solution of the conduction equation, which links a control volume method (CVM) used for the liquid and a boundary element method (BEM) used for the solid, is presented. The necessity of using the BEM for the solid domain is particularly stressed.
