Hydrodynamic Development and Propeller Design Method of Azimuthing Podded Propulsion System

摘要

Hydrodynamic development and propeller design method of Kawasaki's azimuthing podded propulsion system are presented. First geometry of the pod and strut has been optimized successfully by numerical simulation based on computational fluid dynamics solving the Navier-Stokes' equations. The numerical simulation provided exact hydrodynamic interaction between the full propeller and the pod housing. Next the computed results were verified by open water tests and cavitation tests. Lastly the author has proposed how to design optimal propellers mounted on the pod at initial design stages by the practical method based on combination of the measured data and a standard propeller series data.
