摘　　要：针对某大型耙吸船导管可调桨损伤的工程实际,采用自主软件与计算流体力学相结合的方法设计新的导管,在提高敞水效率的同时兼顾空化性能。对该导管的水动力性能进行评估,并结合实船应用验证其效果,研究结果为类似问题的处理提供参考。According to the engineering practical damage of the Ducted Controllable Pitch Propellers(CPP)of a Large Trailing Suction Hopper Dredger(TSHD),a new duct is designed by using the combination of in-house code and Computational Fluid Dynamics(CFD),which takes into account the cavitation performance when improving the open water efficiency.The hydrodynamic performance of the duct is evaluated,and its effect is verified with the actual ship application.The research results provide a reference for the treatment of similar problems.
