摘要
Symmetry-preserving discretization and symmetry-preserving regularization are promising simulation strategies for incompressible flow. In this paper, it is shown that the symmetry-preserving discretization and regularization can be generalized to compressible flow straightforwardly, if the compressible Navier-Stokes equations are rewritten to a new form. The proposed symmetry-preserving methods for compressible flow are validated in a simulation of channel flow. The symmetry-preserving discretization for compressible flow is stable without artificial dissipation and produces accurate results on sufficiently fine grids, which makes the discretization very suitable for direct numerical simulation of compressible flow.
