Abstract : A second order Godunov scheme is described for steady supersonic flow. This scheme, which marches the solution in space, is cast in a finite volume formulation and uses a mesh generated by a multiple zone procedure. Second order accuracy is obtained by computing local slopes and adding a predictor step. The bow shock is fit using the information contained within the Riemann problem. The scheme is applied to body alone and finned configurations for which measurements are available. Reasonable agreement is obtained between experiment and calculation without the use of artificial viscosity or special procedures.
