| Abstract: | n order to solve the aerodynamic problems arising from the re-entry vehicle,one step and two step finite element schemes for the compressible Euler equations are presented,and combined with Lapidus and MacCormack artificial viscosity methiods to capture shock.The results are givin for the hypersonic flow past the blunt body in two dimensions. |
