Abstract
In order to better understand the fluid-structure interaction (FSI) in hydraulic machines, this study aims to numerically investigate the flow around an oscillating hydrofoil with special attention on the effect of unsteadiness on leading edge cavitation. The cavitating flow has been modelled as incompressible with a Shear Stress Transport (SST) turbulence model coupled with a transition model, and with a mass transport equation between vapor and water. The sinusoidal motion of the hydrofoil has...
