Hybrid Continuum-Particle Computation of Hypersonic Flows

Abstract

Development is described of a Modular Particle-Continuum (MPC) hybrid CFD/DSMC code for physically accurate and numerically efficient computation of hypersonic configurations involving mixed regions of continuum and rarefied flow. Recent studies focus on the application and assessment of the hybrid code to complex hypersonic configurations including a cylinder-flare and a blunt capsule. The hybrid method can provide as much as a factor of 12 speedup in comparison to a full DSMC computation while providing almost identical results.
