碩士 / 國立臺灣大學 / 工程科學及海洋工程學研究所 / 99 / In this study, we apply the Computational Fluid Dynamics package software FLUENT to simulate the added resistance of Wigley hull in short waves. Firstly, short waves of three different wave lengths in a tank were generated numerically. Then the model of Wigley hull was set in the wave tank, and force acting on the hull was simulated and the average resistance was obtained. In addition, Wigley hull in the tank of uniform flow was also simulated, and the resistance in calm water was also calculated. Then the difference between the resistance in calm water and the average resistance in waves of these three different wave lengths, i.e. the added resistance in short waves, were obtained.
The simulated results were compared with the existing data of published references. The trends of added resistance vs wave length are quite similar to those of published data, qualitatively and quantitatively. The validity is confirmed to apply the CFD tool of FLUENT to predict the added resistance of a ship in short waves.
