Title: Experimental study on cavitating flow characteristics within cavitation erosion zone
Abstract: The dynamics of high-velocity cavitation flow was investigated experimentally.The experiments were carried out in a rectangular-section cavitation tunnel in the Hydrodynamics Lab of Zhejiang University of Technology.A high-speed video camera was used to visualize the cavitation clouds under different aeration concentrations.And the flow pressure was measured.The characteristics of cavitating flow with bubbles collapse were analyzed based on cavitation number curve.The results show that there are different cavitation characteristics under different aeration concentrations.There was a sudden rise of cavitation number within cavitation erosion zone,along with a large number of bubble collapses.
