Project

The flow over ship propellers is under investigation. In particular propellers of unconventional geometry such as tip-fin propellers are being investigated, in particular with a view to improve efficiency and limit noise and vibration impacts. A comparative study of a tip-fin propeller and a conventional propeller is being carried out. Both propellers are designed for the same ship and the same service conditions. The examination is made theoretically as well as experimentally. The experiments include open water, self propulsion and cavitation tests.

The project focuses on the growing challenge of underwater radiated noise (URN) and its negative impact on the marine environment, especially marine life.

This PhD project at DTU explores underwater radiated noise prediction for marine propellers.
