The flow patterns of cavitating gas-liquid two-phase flow in water exit have been studied experimentally. The complicated processes of cavity's collapse, its re-generation, and cavity's interaction with the free surface, etc. have been observed. For a collapsing cavity, its transparent tail becomes opaque, which may be related to the formation of re-entrant jet. However, in general, the cavity collapses entirely. By using the FLUENT software and VOF method, the flow field is simulated numerically and the results are in agreement with experiment.
