Double time-relaxation kinetic model for compressible turbulence modeling

Advances in Aerodynamics
In this paper, a double time-relaxation kinetic model (DtrKM) is proposed for compressible turbulence modeling on unresolved grids. Within the double time-relaxation framework, DtrKM is extended in the form of generalized Bhatnagar-Gross-Krook model ...
