Similarity law of flowrate for hot-gas ventilated supercavity flows

Abstract

Based on the complete sets of similarity criteria for modelling experiments of exhausted-hot gas ventilated supercavity flows which had been derived by author before, considering the effects of phase changes, a similarity law of flowrate for ventilated hot-gas supercavity flows is found and described in this paper. The effects of phase changes on modelling scheme and ventilated-gas flowrate are studied. The phase changes are the vaporization of liquid water on cavity wall, and condensation of vapor contained in the flows of gaseous mixture within cavity
