A new semi-Lagrangian scheme for the polyatomic ESBGK model that is asymptotic preserving, stiffly accurate, and converges to Navier-Stokes with correct coefficients in the continuum limit.
The UGKWP method decomposes gas distribution functions into hydrodynamic waves and particles for binary-species mixtures, recovers correct transport coefficients via Groppi and Shakhov models, and matches DSMC results in hypersonic tests.
