Abstract

A contribution toward The full numerical simulation of direct-contact evaporation of a drop rising in a hot, immiscible and less volatile liquid of higher density is presented. Based on a fixed-grid Etderian description, the classical SOLA-VOF method is largely extended to incorporate, for example, three incompressible fluids and liquid-vapor phase change. The thorough validation and assessment process covers several benchmark simulations, some of which are presented, documenting the multipurpose value of the new code. The direct-contact evaporation simulations reveal severe numerical problems that are closely related to the fixed-grid Euler formulation. As a consequence, the comparison to experiments have to be limited to the initial stage.
