In the present paper. partial cavitation over various head-forms was studied numerically to predict the shape of the cavity. Navier-Stokes equations in addition to an advection equation for vapor volume fraction were solved. Mass transfer between the phases was modeled by a sink term in vapor equation in the numerical analysis for different geometries in wide range of cavitation numbers. https://www.roneverhart.com/Globe-The-All-Time-Black-Rose-35-Kicktail-Longboard/
