针对特大型水面高速船，采用STAR-CCM+数值仿真软件，对其在静水面以不同航速和侧滑角航行时的流场特性进行仿真计算，获取其流体阻力变化规律和船体周围流场分布特性。结果表明：相对于试验测试结果，数值计算所得总阻力相对偏差不超过4%，摩擦阻力相对偏差不超过1.5%；不同航速直航时，船体所受流场总阻力与航速成正相关，摩擦阻力占比与航速成负相关；不同航速斜航时，船体所侧向力和侧向力矩系数均随航向角增大而增大。研究结果可为大型船舶的总体设计和船型优化提供参考。
For the super-large surface high-speed ship, the STAR-CCM+ numerical simulation software is used to calculate the flow field characteristics when it is sailing in still water at different speeds and different sideslip angles, and to obtain its fluid resistance change law and the flow field distribution characteristics around the ship. Relative to the test results, the relative deviation of the total resistance calculated by the numerical value does not exceed 4%, and the relative deviation of the friction resistance does not exceed 1.5%. When sailing directly at different speeds, the total resistance of the flow field on the hull is directly proportional to the speed. When skewing at different speeds, the lateral force coefficient of the hull both increase with the increase of the heading angle. The research results can provide a certain reference for the design of the same type of ships.
