Non-Equilibrium Time-Relaxation Kinetic Model for Compressible Turbulence Modeling
Non-Equilibrium Time-Relaxation Kinetic Model for Compressible Turbulence Modeling
For the first time, the non-equilibrium time-relaxation kinetic model (NTRKM) is proposed for compressible turbulence modeling on unresolved grids. Within the non-equilibrium time-relaxation framework, NTRKM is extended in the form of modified Bhatnagar-Gross-Krook model. Based on the first-order Chapman-Enskog expansion, NTRKM connects with the six-variable macroscopic governing equations. The first …
