The Detached Interphase Simulation

Abstract

This work presents a new model based on the Mixture Model and the Volume of Fluid method capable to manage flows with different scale of interphases respect to a measure of the mesh. The model relies on the concept of Detached Interphase Simulation (DIS) or the switching of the base models along the domain as an analogy of the Detached Eddy Simulation (DES) methods used for turbulence simulation. The model is implemented using the OpenFOAMR libraries and the obtained solver is then tested in several cases taken from the literature and proposed by the authors. In order to evaluate the performance of the model new quantitative measures are also proposed. The analysis of the results shows that the DIS model performs better than the base models with different levels of improvement related to the fluids density ratio.
