Title: A volume of fluid based method for fluid flows with phase change

Abstract

Boiling flows are ubiquitous in the energy and processing industries due to the fact that phase change processes are an efficient way to transport heat. Despite decades of research there are still many aspects of boiling flows that are not well understood. This paper presents a numerical method directed towards the simulation of flows with mass transfer due to changes of phase. The authors use a volume of fluid (VOF) based interface tracking method in conjunction with a mass transfer model and a model for surface tension. The bulk fluids are viscous, conducting, and incompressible. A one-dimensional test problem is developed with the feature that a thin thermal layer propagates with the moving phase interface. This test problem isolates the ability of a method to accurately calculate the thermal layers responsible for driving the mass transfer in boiling flows. The numerical method is tested on this problem and then is used in simulations of horizontal film boiling.
