摘要

•An efficient scheme is developed with CPR framework and gas-kinetic flux solver.•The inviscid and viscous fluxes are coupled and computed uniformly.•It adopts an efficient two-stage fourth-order time stepping method.•It is fourth-order accurate in both space and time on triangular meshes.•It has subcell discontinuity resolution through a robust SCFV limiting procedure.
