Nonequilibrium flow simulations using unified gas-kinetic wave-particle method [PDF]

open access: yesAIAA Journal 62 (4) (2024) 1411-1433, 2023
Nonequilibrium flows are common in aerospace engineering, and numerical simulations are vital in understanding non-equilibrium flow dynamics in spacecraft flight. The unified gas-kinetic wave-particle (UGKWP) method has been developed for multi-scale flow simulation, which models the coupled particle transport and collision within a numerical time in ...
