Abstract
The characteristics of ventilated cavitating flow behind a circular cylinder is investigated by numerical simulation and the cavity interface is captured by the coupled level-set and volume of fluid method. The interaction between the ventilated cavitation and vortex structures are investigated. In particular, the bubble identification method is applied to study the bubble distribution and bubble behaviors in the wake.
