Heat and mass transfer analogies for evaporation models at high evaporation rate

Abstract

In the framework of anti and deicing applications, heated liquid films can appear above the ice thickness, or directly above the wall. Then, evaporation plays a major role in the Messinger balance and evaporated mass has to be predicted accurately. Unfortunately, it appears that existing models under-estimate evaporation at high temperature. In this study, different evaporation models at high evaporation rates are studied. The different hypothesis on which these models are built are discussed for high evaporation rates: Chilton- Colburn analogy and non-zero blowing velocity at the film/air interface. These models are compared with a solution obtained by a finite volume approach where boundary layer equations are solved.
