Efficient Tools for Prediction of Performance and Design of Marine Propulsors
Abstract
Computationally efficient methods for the analysis or design of marine propulsors are furtherdeveloped and improved. The main objectives of this proposal are: (a) to model unsteady developed tip vortex cavitation together with sheet cavitation on propeller bladesvia a panel method (PROPCAV), (b) to evaluate the acoustic pressure field induced by a wetted or cavitating propeller on and far away from the hull, by using a boundary element method which takes into consideration the effect of the speed of sound (BLADAC), (c) to include a turbulence model within our viscous vorticity equation method (VISVE) in the case of wetted and cavitating flows around propellers, and (d) use our analysis tools together with our blade optimization method (CAVOPT-3D) to design open, ducted, or counter-rotting propellers for given hull geometry and conditions.
