A Two-Dimensional Relaxation Scheme for the Hybrid Modelling of Gas-Particle Two-Phase Flows

Abstract : This paper presents a two-dimensional relaxation scheme for the hybrid modelling of two-phase gas-particle flows. The method is grounded on a previous relaxation scheme that has been proposed to cope with one-dimensional flows. One of the main difficulties here is due to the fact that the Reynolds tensor occuring in the Lagrangian framework is highly anisotropic. The interface relaxation scheme mimics a previously proposed "relaxation scheme" that involves GNL fields. The method is described and its main properties are given, including a short stability analysis, and numerical results are eventually provided.
