Abstract
Ship fins stabilizer is a kind of anti rolling ship technique that could produce lift with initiative swing of fins at zero forward speed, and the lift could counteract the rolling forces of ocean waves. The method that fin stabilizer is used to anti rolling ship is different from the conventional theory of anti rolling ship at zero speed, so it's a kind of new theoretics. In order to study the process of lift generation of fin stabilizer at zero speed, numerical simulation is made by the CFD software for the NJ5 fins stabilizer from Harbin Engineering University. The result shows that the method is powerful. The practical fluid mechanical experiment can be carried through and the control strategy can be researched under the guidance of this method.
