中文摘要：

研究船舶在浅水域的低速横向漂移运动对研究船舶停靠运动特性具有重要意义。船舶停靠通常是一个低速慢漂的过程,在这个过程中,由于船舶特定的运动形式和几何形状,粘性水动力起主要作用,而兴波很小,其影响可以忽略,可以将自由面作为刚壁处理,从而使问题简化并大大减小数值计算的计算量。文中以标准Wigley船型为对象,对船舶在浅水中横向漂移运动的粘性流场和水动力进行了计算。为了得到准确、稳定的计算结果,分别选取了不同的计算区域、网格数量和湍流模型进行计算,并将计算结果与他人的计算结果和模型试验结果进行了比较,确定了模拟船舶低速停靠运动粘性流场的有效的数值方法。

英文摘要：

Study on the ship＇s lateral motion at low speed in shallow water is significant for investigating the ship performance during berthing when a ship usually moves laterally at low speed. In this paper, the viscous flow field and hydrodynamic force acting on a standard Wigley hull moving laterally in shallow water are calculated. Different computational regions, grid numbers and turbulent models are selected to find an exact and stable numerical solution.The numerical results are compared with the experiment results and other calculated results published in literatures, and an effective numerical method for simulation of the viscous flow around a ship in berthing motion at low-speed is established.
