Hybrid recursive regularized thermal lattice Boltzmann model for high subsonic compressible flows
Journal of Computational Physics(2019)
摘要
•A thermal LB model has been developed on standard lattices for subsonic to sonic compressible flows.•An extension of the Hybrid Recursive Regularized (HRR) collision model is developed for compressible flows.•The defect of Galilean invariance and non-hydrodynamic oscillation is effectively eliminated by HRR collision model.•Excellent agreement is shown for the simulation of compressible laminar flow over flat plate, as well as isentropic vortex convection.
