摘　　要：选取一超大型油船,利用CFD软件与参数优化相结合,运用滑移网格模拟桨舵及船桨舵的一体运动,综合分析船舶的推进性能。与试验结果对比,螺旋桨敞水及船桨舵自航的CFD结果与实验值吻合度高。在此基础上,通过参数化建立舵球的模型,分析舵球对桨舵系统敞水性能的影响。对筛选方案进行整体自航对比,评估舵球的节能效果。For a super-large oil tanker,combining CFD software with parameter optimization,the sliding grid was used to simulate the integrated motion of the propeller and the rudder,so as to comprehensively analyze the propulsion performance of the ship.The CFD results of the open water of the propeller and the self-propulsion comparison data of the ship were in good agreement with the experimental values.The parametric model of the rudder ball was established to analyze the influence of the rudder ball upon the open water performance of the rudder system.The initial screening scheme was compared with the overall self-propulsion,and the energy-saving effect of the rudder ball was evaluated.
