abstract

To investigate the capabilities of using a viscous-flow solver to calculate current or manoeuvring forces on ship hulls, calculations have been conducted for a test hull under several oblique inflow conditions. All calculations were performed with a single grid topology to reduce the amount of grid generation time. Verification and validation of the predicted loads and flow around the hull has been performed through grid refinement studies and comparison with experiments and results from previous calculations. Furthermore, the influence of unsteady behaviour on the results for large inflow angles is shown. Conclusions are drawn regarding the accuracy of the results and recommendations for improvements and further work are given.
