航行中波浪水池的数值动力学研究

The research on numerical dynamics of wave basin in sailing ship

利用数值波浪水池进行船舶航行预报,是计算船舶水动力的重要方法。本文首先建立船舶水池的数值控制方程,然后利用网格划分对船舶周围的流场进行划分,最后利用Wigley-III船舶模型计算船舶在规则波中航行时受到纵向、垂向和纵摇力矩的系数,将其与势流理论(3D-BEM)和DUT计算方法相比较。

It' s an important method to calculate the hydrodynamic force of ships using numerical wave tank to predict the ship navigation. In this paper,firstly establish the numerical control equation of the ship water tank. Then,the flow field around the ship was divided by the mesh generation. Finally,the Wigley-III ship model was used to calculate the longitudinal,vertical and pitching moment of the ship in regular waves,then compared with the potential flow theory and the DUT calculation method.
