Project Details

Description

The design of marine screw propellers has two hydrodynamic goals, maximise efficiency and minimise propeller induced vibration and noise. This project aims at the development of design methods and design database for optimum trade-offs between maximising efficiency and minimising induced noise and vibration.
To this end a database af benchmark quality of model tests and full-scale observations is built up. Thises data are used to validate improved and advanced Computational Fluid Dynamic (CFD) tools developed in this project. The CFD tools enable accurate prediction of the flow and cavitation inception in the leading edge and tip regions. This approach allows cavitation free designs of high efficience.
