Compressibility Effects on Cavitation in High Speed Liquid Flow : Second Report-Transonic and Supersonic Liquid Flows

抄録

Some notable features of normal and oblique shock waves of supersonic liquid flow are clarified and also the close relations of cavity streamline to the flow turning by expansion wave are pointed out. And then after defining the Mach number range for transonic and supersonic liquid flow by using the critical Mach number, the governing equations of parabolic and hyperbolic types for velocity potential are analytically solved by local linearization technique. Compressibility effects on the cavity characteristics of symmetrical wedge are clarified through the Mach number range . Comparisons are also made with the results from oblique shock relations.
