Numerical Simulation of Unsteady Cavitating Flow over Cone Geometry Using Large Eddy Simulation Method

Engineering interest in natural and ventilated cavities over submerged bodies has led researchers to study cavitation . In this study , cavitating flow over a cone of 45 degree vertex angle is simulated via a simple proposed cavitaion model and large eddy simulation as turbulence. The giverning equation are the unsteady incompressible viscous Navier Stokes equations . The proposed method includes the combination of a source and a sink of vapor through a dissipation term. The comparison between the obtained numerical results and the experimental data shows that the cavity characteristics are well simulated.
