EXPANSION FLOWS ON WALLS WITH NONEQUILIBRIUM CONDENSATION

The streamtube method for supersonic expansion flows on walls with nonequilibrium condensation is developed incorporating the radius dependence on the droplet growth rate. In the presence of an embedded, frozen, oblique shock wave arising from supercritical heat addition from condensation, the method is supplemented by the derived oblique shock relations, and the oblique shock location is determined by employing a shock fitting technique. Some advantages of the proposed streamtube method are explored in comparison with the numerical method of characteristics.
