Firstly the freestream Mach number for subsonic liquid flow is defined as being smaller than the lower critical Mach number in which the critical condition can be found on the cavity streamline The governing equation of elliptic type for velocity potential is solved by local linearization technique and then the corresponding relation are derived between subsonic and incompressible liquid f1ows. Compressibi1ity effects are minutely discussed on the cavity characteristics of symmetrical wedge through the Mach number range and also comparisons are made with the former linearized analysis.
