A Hybrid CFD-DSMC Method of Modeling Continuum-Rarefied Flows

A Hybrid CFD-DSMC Method of Modeling Continuum-Rarefied Flows

A hybrid method of simulating high-speed, non-equilibrium flows solves the NavierStokes equations using a Computational Fluid Dynamics (CFD) model in regions of the flow where properties are continuous and a statistical Direct Simulation Monte Carlo (DSMC) model in regions where properties are non-continuous and thermal nonequilibrium exists. The hybrid method …
