摘　　要：船舶液舱中液体晃荡现象已引起人们的深刻关注,液体晃荡载荷与效应成为航行中载液船舶安全性评估的重要内容之一。该文基于Level-set法,对一矩形液舱的两种工况下舱内的液体晃荡进行了数值模拟。通过计算,得到了液面起伏和压强的时间历经,结果显示Level-set方法可有效地模拟液体晃荡问题。Liquid sloshing phenomenon in a liquid tank mounted on ship has caused people＇s profound attention and the sloshing loads and effects have become the important content of the safety evaluation of a sailing liquid cargo. In this paper, numerical simulation of liquid sloshing in a rectangle liquid tank forced sway and rolling is performed based on Level-set method.The elevation of free surface and the pressure time history are obtained. The results show that the Level-set method can be used to simulate liquid sloshing effectively.
