Experimental and numerical investigation of ventilated cavitating flow with special emphasis on gas leakage behavior and re-entrant jet dynamics
TL;DR: In this paper, the authors investigated the ventilated cavitating flow structure by combining experimental and numerical methods, and the results showed that when the gas entrainment coefficient Qv is constant, two typical mechanisms of the gas leakage exist at different Fround numbers Fr, namely toroidal vortices mode and two hollow tube vortice mode.
