When a space vehicle returns into the earth atmosphere, the gas temperature around the vehicle becomes very high owing to mainly shock compression. To protect the vehicle from such high temperature environment, the problem on the aerodynamic heating should be analyzed precisely. In the present numerical computations, the high temperature air-flow with the real gas effects such as dissociation and ionization is studied to simulate hypersonic flows produced in a conical nozzle of the gun-tunnel placed at the Aoyama Gakuin University. The 2-D Euler code is used together with TVD scheme for shock discontinuity. To simulate the high temperature air-flow produced in a small hypersonic gun-tunnel located at Aoyama Gakuin University, numerical computations are performed by applying the 2-D Euler code with TVD scheme. The real gas effects of high temperature air with dissociation and ionization are taken into account.
