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.
