 Abstract

Predicting the equilibrium between a ship’s required thrust and resistance is a complicated problem. Shipyards have to pay big penalties when a ship does not run at its design speed at a specified required power. An accurate prediction of the ship’s self-propulsion point is thus of huge importance. In the determination of the self-propulsion point model scale tests are still decisive. An alternative for these model tests is found in CFD methods. This thesis work has provided an analysis of such a method: a hybrid coupling between a viscous (RaNS) solver for the ship’s hull and a potential flow method (BEM) for the propeller.
