摘　　要：采用基于RANSE的数值波浪水池技术和数值拖曳水池技术,针对75 000 t船模型开展带有纵摇和横摇运动的自航CFD模拟研究。首先进行静水中的船模阻力和自航CFD模拟,通过与模型试验结果比较,初步验证了文中的CFD模拟方法 ;随后开展不同运动状态下是否带有舵附推力鳍的船模自航CFD模拟,并对该种状态下的船模阻力、运动响应以及船后螺旋桨的推力和扭矩等进行分析,获得相关变化特性。该项研究对于运动中船舶快速性研究和预报等,具有较好的指导意义和参考价值。The CFD simulations of the self-propulsion test with pitch and rolling for a 75 000 t model ship were carried out by the numerical wave tank technology and numerical towing tank technology based on RANSE. The resistance test and self-propulsion test simulations for the ship in calm water were firstly performed and compared with the model test results to preliminarily validate the CFD simulation method. Then, the self-propulsion tests for the model ships with or without rudders with additional thrust fins under the different motion modes were simulated to analyze the resistance and motion responses of the model ship, and the thrust and torque of the aft propeller, resulting in the relevant variation characteristics. The research can provide guidance and reference for the study and prediction of powering performance of ships in waves.
