Hypersonic Flow with Strong Blowing

A validation study is presented for a numerical code which calculates a two-dimensional steady-state solution for inviscid hypersonic flows in the presence of strong surface blowing. A higher-orde: Godunov-type finite-volume approach is used to discretize the inviscid Euler equations. Interface values of the state quantities are reconstructed nsing a monotone interpolation technique suggested by Koren, based on Van Leer’s kappa scheme. The interface fluxes are computed using Roc’s upwind-biased flux-difference splitting technique. The time-differencing algorithms used are a locally implicit, linearized Gauss-Seidel itcration scheme and an explicit multi-stage scheme with optimized short-wave damping. The results of the numerical calculations are compared with analytical solutions obtained for strong blowing along a flat plate and a wedge with an inversesquarc-root injcct,ion-velocity distribution
