Conventional CFD is computationally affordable but loses accuracy in hypersonic rarefied and non-equilibrium flows. Particle-based kinetic methods such as DSMC provide higher physical fidelity but are often too computationally expensive for routine engineering design. Grey Hawk Research is developing simulation technology that bridges this gap.<\/span><\/p>\n
