Abstract
A sharp interface cavitation modeling methodology is presented. A simplified Rayleigh-Plesset equation is used to obtain the phase change rate from the local pressure. The phase change rate is expressed as mass flux jump conditions. The phase interface is tracked using a second-order volume-of-fluid method with a constructed level set function. The interface normal velocity jump is extended into the flow field using a fast marching method. A ghost fluid method is used to prevent difficulties computing high-order derivatives near the interface. Two separate intermediate velocity fields from the momentum equation are solved considering the velocity jump conditions. Some preliminary results will be demonstrated to show the promise of the present approach.
