Abstract
A flow model of two-phase media composed of a liquid and spherical gas bubbles is developed for computing high-speed cavitation flows. State equations of liquid and gas phases are employed to relate density with pressure, and a set of governing equations are solved by the CIP-CUP method. Cavitation inception is then evaluated by a gas volume fraction according to a bubble radius in a local field. As an example of computation, an orifice nozzle flow is treated, and the reliability of the computation is estimated by comparison with experimental data.
