Shocks due to high pressure ratio are computed for both inviscid and viscous flows, using an original two point subsonic-supersonic solving algorithm. Unsteady boundary consitions are considered, to simulate highly unsteady flows. The advantages of this method, in this particular case, upon a McCormack predictor-corrector scheme are developed. Comparison between the inviscid flow and the viscous flow shows that the viscous effect have little influence when the geometry of the nozzle is too large
