Direct simulation of film boiling including electrohydrodynamic forces

Abstract

This paper presents simulations of film boiling including electrohydrodynamic forces. The coupled level-set and volume-of-fluid interface tracking method is augmented with a mass transfer model, a model for surface tension, and electrohydrodynamic force terms. The bulk fluids are perfect dielectrics-viscous, heat conducting, and incompressible. We explore film boiling on a horizontal surface and we consider the effect of an applied electric potential. The electrodynamic equation for the evolving electric field is solved in both phases during saturated horizontal film boiling, and the effects are described.
