As the first step of the study of cavitation in the tip leakage flow of turbomachinery, experimental and numerical studies were carried out to investigate the characteristics of cavitation in the 2-D unsteady tip leakage flow. The numerical method was constructed by combining the vortex method with taking into account the effects of cavity growth. Three types of cavity models are examined. It is shown that one of them simulates the location and the size of the cavity fairly well. Comparisons with experiments are made for three values of initial pressure and for three values of tip clearance. The model can predict those effects and it is expected that the present model is useful for the estimation of cavitation characteristics of 3-D tip leakage flow.
