Title: A Unified Multi-Dimensional Gaskinetic Hybrid BGK-DSMC Method for Nonequilibrium and Chemically Reacting Flows
Agency: NASA
Contract: NNX09CF09P
Award Amount: $99,928.00
 

Abstract:

A consistent and accurate Hybrid gaskinetic BGK and DSMC method, valid in the full Knudsen number (Kn) range, is proposed as a 3D tool to handle hypersonic aerothermodynamics from continuum to thermochemical nonequilibrium and ionized/plasma flows. By domain-decomposition, the proposed method will provide adjoint but automated sub-domain solutions by solving the gaskinetic BGK method of Xu (BGKX) and DSMC in their respective low and high Knudsen regimes, therein the BGKX and DSMC solvers have been proven comparatively efficient for thermo-chemical nonequilibrium flows with accurate heat rate prediction. The proposed approach is considered an advancement in rarefied gasdynamic methodology in that: BGKX is efficient for near continuum flows, say 0
