Effects of Turbulence and Mass Transfer Models on Dynamics in Cavitating Propeller Flows

Tuomas Sipilä; Ville Viitanen

Abstract

In the marine applications, cavitation occurs most typically in ship propeller flows. Cavitation causes detrimental phenomena on ships and the environment. Cavitation increases vibrations to the ship structures, which can be harmful to machinery and disturb people on board. Cavitation can be erosive to propellers and rudders. In severe cases, damages can shorten dry-docking interval and cause significant costs to the ship owner. Finally, cavitation is the most significant source of underwater noise in ships. Underwater noise emitted from shipping has become a concern due to increased environmental awareness. There is rising pressure to restrain the acoustic footprint of shipping.
