Description
Summary:This paper addresses the prediction of ship performance in waves by means of RANS-based CFD. Lately, much attention has been given to modelling the complex geometry (moving hull and rotating propeller) which can sometimes distort or suppress the importance of the underlying physics. The approach here is to subject a fixed hull to waves and study how the flow around the hull is affected and what this means for the inflow to the propeller and the resulting propulsive performance of the ship. This study provides a straightforward approach for gaining insight into how hull design can influence the performance of ships in waves.
