A new reconstruction scheme for the computation of inviscid compressible flows on 3D unstructured grids

摘要

A finite-volume method for the solution of three-dimensional inviscid compressible flows on cell-vertex tetrahedral meshes is proposed. A higher-order-accurate upwind discretization is obtained by using a new linear reconstruction and a standard flux-difference-splitting scheme. The method is validated by computing the subsonic flow in a 90° rectangular elbow with a total pressure gradient imposed at inlet.
