| Abstract: | A finite difference scheme based on flux difference splitting is presented for the solution of the two-dimensional Euler equations of gas dynamics in a generalized co-ordinate system. The scheme is based on numerical characteristic decomposition and solves locally linearized Riemann problems using upwind differencing. The decomposition is for a generalized co-ordinate system and a convex equation of state. This ensures good shock-capturing properties when incorporated with operator splitting and the advantage of using body-fitted co-ordinates. The resulting scheme is applied to supersonic flow of real air' past a circular cylinder. |
