Full TextAbstract
Clark-Y hydrofoil is reported using computational fluid dynamics (CFD) technique. This simulation is performed using the large eddy simulation (LES) turbulence model. We applied an incompressible LES modeling approach based on an implicit method for the subgrid terms. To apply the cavitation model, the flow has been considered as a single fluid, two-phase mixture. A transport equation model for the local volume fraction of vapor is solved with the LES model and a finite rate mass transfer model is used for the vaporization and condensation processes. The volume of fluid (VOF) method is applied to track the interface of liquid and vapor phases. This simulation is performed using a two phase solver available in the framework of the OpenFOAM (open field operation and Manipulation) software package, namely “interPhaseChangeFoam”. The solver is based on the finite volume method. Simulation is performed for the cloud and super cavitation regimes. The results of our simulation are compared with the experimental data and the accuracy of the simulation has been investigated.
