Three dimensional high-order gas-kinetic scheme for supersonic isotropic turbulence II: coarse-grained analysis of compressible $K_{sgs}$ budget

Guiyu Cao, Liang Pan, Kun Xu

The direct numerical simulation (DNS) of compressible isotropic turbulence up to the supersonic regime $M{a}_t=1.2$ has been investigated by high-order gas-kinetic scheme (HGKS)…
