Numerical Analysis of Supercavitating flows over 2D and 3D bodies by Large Eddy Simulation

In this paper, The Kunz’s cavitation model is utilized to simulate supercavitating flow over a disk. The multiphase Navier–Stokes equations are solved for the mixture of liquid and vapor. The vaporization and condensation processes are controlled by Kunz cavitation model. The Large Eddy Simulation, LES, model is selected which is found to be suitable in comparison with the standard k-ε model. Close agreement between the obtained results and the available experimental data shows LES can improve the accuracy of this cavitation model. It can be concluded that the utilized model describes the cavitation behavior in 2 and 3D geometries well.
