Abstract

The numerical solution of the laminar Navier-Stokes equations for high-speed flows is considered. The equations are written in non-conservative form, and the shocks treated by a shock-fitting technique which allows accurate predictions of the shock location and of its propagation velocity. Since a critical point of the numerical calculations of viscous high speed flows is the prediction of the interaction between shock wave and boundary layer, numerical tests are performed to assess the capability of the present technique to handle these phenomena in both weak and strong interaction regimes.
