Numerical Simulations of the Cavitating Flow on a Marine Propeller

Abstract

This paper deals with numerical simulations of the cavitating flow around a marine propeller operating in open water but mounted on an inclined shaft.The investigation is mainly based on both Large Eddy simulation (LES) and Unsteady Reynolds-Averaged Navier-Stokes (URANS) in combination with a Volume-of-Fluid implementation to capture the liquid-vapour interface and a transport equation-based method for the mass transfer between the phases.Potential flow solver result will also be included to offer a complete picture of the general behaviour and capabilities of a range of computational methods with different levels of detail.Highspeed video recordings from experiments are available for detailed inspection.
