摘　　要：本文应用MAC方法对矩形容器内一层和两层流体由水平激振所引发的晃动进行了数值模拟。计算取与容器固联的坐标系,视激振加速度为质量力,计算结果在流场的形态等方面与实验观测基本一致。In this papar, the numerical simulation of liquid sloshing excited by an lateral motiopn of the rectangular container has been performed by using MAC method. The calculating coordinate system is fixed with the container. We regard the excited acceleration as an mass force. The comparison with the test results shows that, the numerical simulation method is feasible and successful.
