| Abstract: | Numerical simulations of the flow fields around a body overtaking a shock wave are carried out with the two dimensional unsteady compressible Navier Stokes equations.A domain decomposition method and the FSA(Fortified Solution Algorithm) are employed to reach sufficient grid resolution.Two test cases,the supersonic overtaking and the subsonic overtaking are considered.By the contrast with the results obtained by original method,the FSA is a good tool which can handle the complicated configuration and improve the grid resolution simply and usefully. |
