摘要
为研究航道岸壁对船-船干扰作用的影响,该文采用非定常雷诺平均纳维-斯托克斯(Unsteady Reynolds Averaged Navier-Stokes)方程与动态重叠网格耦合的方法,对限制航道中航行船驶过系泊船全过程进行数值模拟。网格依赖性分析显示数值结果随网格尺寸减小迅速收敛,且水动力的数值结果与试验数据吻合良好,说明该数值方法可以较准确地预报限制航道船-船干扰作用。在此基础上,对不同系泊船离岸距离下的航行船-系泊船干扰作用进行数值计算。结果显示:随着系泊船与岸壁距离的减小,在岸壁效应和船-船干扰作用的共同影响下,船行波更加显著,系泊船纵向力和姿态变化幅度更大,而横向力、横摇力矩和艏摇力矩的幅值反而减小。
In order to investigate the bank effects by the channel wall on ship-ship interactions,in the study the whole process of a ship passing a moored ship in restricted waterways is simulated by using unsteady Reynolds Averaged Navier-Stokes(URANS)method and the dynamic overset mesh technique.The mesh dependence analysis shows that the numerical results of hydrodynamic quantities converge rapidly as the mesh size decreases,and the numerical results agree well with the test data,indicating that the present method is reliable for predicting ship-ship interactions in restricted waterways.Based on the validated method,the interactions between the passing ship and the moored ship with different moored ship-wall distances are numerically simulated.The results indicate that as the ship-wall distance decreases,the ship-generated waves by the passing ship are more remarkable,and the amplitude of the surge force on the moored ship and the ship attitudes increase remarkably under the combined impacts of bank effects and the ship-ship interactions.However,the amplitudes of sway force,roll moment and yaw moment induced by the passing ship decrease in contrast.
