摘要: A low storage, computationally efficient algorithm for the solution of compressible Euler equations on unstructured tetrahedral meshes is developed. The takes form a centred scheme with explicit addition high accuracy artificial viscosity and advanced to steady state by means multi-stage time stepping method. side based data structure which employed enables clear connection be established between proposed upwind cell vertex schemes meshes. computational efficiency procedure improved incorporating an multigrid acceleration procedure. number flows practical interest are analysed demonstrate numerical performance approach.
