Full TextAbstract
In this paper simulation of cavitating flow over the Clark-Y hydrofoil is reported. This simulation is performed using the large eddy simulation (LES) turbulence model. To apply the cavitation model, the flow has been considered as a single fluid, two-phase mixture. A compressive volume of fluid (VOF) method is applied to track the interface of liquid and vapor phases. This simulation is performed using a finite volume, two phase solver available in the framework of the OpenFOAM package. Simulation is performed for the cloud cavitation regime. We compared the results of two different mass transfer models, namely Kunz and Sauer models. The results of our simulation are compared with the experimental data for cavitation dynamics, starting point of cavitation and force coefficients. Suitable accuracy has been observed.
