摘　　要：船/桨/舵相互干扰研究在传统船型优化设计和新船型的开发中具有重要意义。应用计算流体力学(CFD)方法对带桨的KCS集装箱船及带桨和舵的KVLCC2油船非稳态粘流场进行了数值模拟,其中船桨舵干扰计算分别采用动量源法、MRF法和滑移网格法,分析研究了各方法及其结果的异同。研究表明不同模拟计算方法均能合理预报出船/桨/舵相互干扰相互作用下速度场和压力场分布等详细流场信息,可用于计算船体阻力、表面压力和桨盘面伴流等。通过这种详细的数值模拟研究,可以更好地理解复杂流动干扰现象。Research of hull/propeller/rudder interaction is significant for ship optimization and development of conventional and new types of hull form.Based on computational fluid dynamics（CFD） method,numerical simulations of unsteady viscous-flow are performed for containership KCS with propeller and tanker ship KVLCC2 with propeller and rudder,in which simulations of hull/propeller/rudder interaction are carried by adding momentum source,MRF（Moving Reference Frame） method and sliding mesh method respectively.The merit of each method is discussed.The researches show that the reasonable detail fluid flow field information such as velocity,pressure distribution can be obtained and ship resistance,pressure on whole ship hull,etc.can be calculated.By the present detailed numerical simulation for flow field around ship one can gain better understanding of the complex flow interaction phenomena of hull/propeller/rudder.
