Investigation of Cavitation Bubble Dynamics Considering Pressure Fluctuation Induced by Slap Forces

Cavitation erosion is induced by the penetrating pressure from implosion of cavitation bubbles nearby solid boundary. The bubble evolution and subsequent collapse are especially important to evaluate degradation boundary materials. dynamics equation taking into account influence distance between formulated investigate effect wall on process. fluctuation slapping forces adopted dynamic characteristics. Negative period which reflects vibration velocity gap clearance also has large dynamics. effects standoff distance, initial radius negative collapsing shock discussed. Maximum increases with radius, while decreases both them increase period.
