Comparison and validation of multi phase closure models

The purpose of this paper is to propose a simple (one or two parameter) multiphase flow model, suitable for the description of Rayleigh–Taylor and Richtmyer–Meshkov mixing layers. We justify model closure assumptions in this model by comparison to Rayleigh–Taylor and Richtmyer–Meshkov simulation data. We show that the relative errors related to model closure terms are about 10%, and are about two to four times smaller than related closure models of Abgrall and Saurel.
