Abstract : The flow of a two phase mixture of air and very small ice particles (approx. 100A) through an oblique shock wave, produced by a wedge, was studied experimentally and theoretically. Measurements of oblique shock angle and shock curvature, obtained from schlieren and shadow photographs, were used to determine initial particle evaporation rates behind the shock. Measured oblique shock angles are found to vary from the frozen angle at the leading edge of the wedge, to an equilibrium angle far from the leading edge. The experimental findings are in agreement with theoretical values computed for spherical particles evaporating in free molecular flow. (Author)
