Modelling of Sheet Cavitation on Hydrofoils and Marine Propellers using Boundary Element Methods

In this Thesis inviscid models based on the Boundary Element Method are developed for the calculation of partial and super sheet cavitation on hydrofoils and marine propellers. The two and three-dimensional, steady and unsteady cases are considered. The model is found to be fast, robust and accurate, hence suitable for the implementation of a cavitation model. A three-dimensional cavitation model without re-meshing is implemented and extensive numerical studies are performed for hydrofoils and propellers. The numerical results for cavitating flow show good agreement with the experimental data for the MARIN S-Propeller and the INSEAN E779A propeller.
