摘　　要：为模拟考虑自由表面影响的船舶联合运动条件下的粘性流体流动,通过控制体积法求解非定常RANS方程以及六自由度(6DOF)运动方程,同时采用VOF模型、SST k-ω湍流模型以及滑移网格建立了一种预测船间水动力相互作用行为的方法,利用该方法开展孤立Wigley船体、孤立KCS船体、相互作用Wigley船体以及相互作用KCS船体的水动力特性研究,讨论了不同速度比对船间水动力的影响规律。结果表明:本文建立的船间水动力相互作用模型与文献结果符合较好,说明本文方法可有效解决船间水动力预测问题;对于静止目标船,追越过程中目标船受到的横向力主要受船间纵向距离对其产生的影响;对于航行船舶,追越过程中相对航行速度将会对目标船受到的横向力产生影响。In order to simulate the viscous fluid flow under the condition of joint motion of ships considering the influence of free surfaces,the unsteady RANS equation and the six degrees of freedom(6DOF)equation of motion are solved by the controlled volume method,and the VOF model,SST k-co turbulence model and slip Grid established a method for predicting the behavior of hydrodynamic interactions between ships.Using this method,the hydrodynamic characteristics of isolated Wigley hulls,isolated KCS hulls,interacting Wigley hulls,and interacting KCS hulls were studied,and different speed ratios were discussed.The law of influence on the hydrodynamics between ships,the results show that the hydrodynamic interaction model between ships established in this paper is in good agreement with the results of the literature,indicating that the method in this paper can effectively solve the problem of hydrodynamic prediction between ships;for stationary target ships,the overtaking process The lateral force on the target ship is mainly affected by the longitudinal distance between the ships;for a sailing ship,the relative sailing speed during overtaking will have a great influence on the lateral force on the target ship.
