摘　　要：本文基于开源代码OpenFOAM,采用基于全非线性势流方法与粘性流方法耦合的混合模型,结合桨舵推进模型,模拟单桨船在波浪中的回转和Z形操纵运动。外场采用全非线性势流方法(FNPT)模拟波浪水池,内场采用粘流方法模拟波浪与船舶相互作用,采用考虑波浪影响的桨舵力学模型计算航行中的桨舵推进受力,实现船舶在波浪中六自由度操纵运动的仿真。采用KVLCC2模型用于数值模拟,通过自航试验对比验证方法的有效性。模拟初始横浪条件下船舶波浪中操纵运动,通过改变波长研究和分析横浪下波长对船舶回转性能和机动性能的影响。Based on the OpenFOAM,a hybrid model coupling fully nonlinear potential flow theory(FNPT)with viscous flow method,and the propeller-rudder mode,the turn and zigzag maneuvers of a single-screw ship in waves were simulated.The FNPT was used to simulate the wave tank in the external field,while the viscous flow method was used to simulate the interaction between waves and ships in interal field.Then,the 6DOF ship maneuvers in waves was simulated.The KVLCC2 model was selected for simulation,and the method was validated by the tank test,and the maneuvers in beam waves were simulated.By various wave-lengths,the effect of wavelength on the ship maneuvering performance in beam waves was investigated.
