Abstract

This paper discusses the ongoing extension of the DLR TAU Code with a multiphase flow model. The reasoning behind choosing a Statistical Eulerian Eulerian (SEE) model with Interfacial Area Transport Equation (IATE) is covered. Properties of the model are introduced, especially concerning the less known IATE concept which provides information about interphasic IA available in a computational cell. This allows for a more elaborate sub grid scale modelling. An IA convection velocity is derived which holds for the limiting cases of stratified flow and disperse flow. Interfacial growth due to velocity gradients is investigated. A new IA detection term resolves ambiguities with boundary conditions. As an exemplary application, a proof of concept of spray injection simulation is discussed.
