摘　　要：对船舶在近岸环境下航行时侧推器的水动力性能进行数值模拟研究。建立艏艉侧推器与船体的整体模型,利用基于RANS方程求解的粘性流数值方法,采用MRF模型,计算不同航速下艏艉侧推器的性能参数、侧推器附近流场,以及船舶在近岸航行时的横向力与艏摇力矩。结果表明,近岸航行时侧推器的实际效能会因船速的变化而变化,船速的不断增加会使船舶与岸壁之间的吸引力超过侧推器的推力,从而导致碰撞。The hydrodynamics performance of side thrusters of ship sailing near-bank is studied numerically.The integrated model of side thrusters and hull is established,and MRF mode is adopted.The flow field near the thrusters and the hydrodynamic lateral forces and yaw moments on the ship nearing the bank are calculated for different speeds,and then performance parameters of the bow and astern thrusters are obtained.The results show that the actual performance of side thrusters under near-bank sailing varies with ship＇s speed,and the attractive force between ship and bank may exceed the thrust with the increase of the speed,which may lead to collision.
