| 摘 要： | 利用两相流模型对带自由面的流动问题进行了数值模拟，计算了舱内水体晃荡对水舱横摇运动的影响。利用计算流体力学软件ＣＦＸ－４，模拟了舱体大幅横摇时水的晃荡、翻卷和重入，通过对不同的舱内水深、不同摇幅的水舱强迫和自由晃荡问题的数值计算，发现舱内水深对晃荡力矩有重要影响，在给定的计算频率下，浅水的影响比深水更大。

| Abstract: | The numerical analysis of the sloshing effects on ship roll motion was done with the multi phase model for the flow problem with free surface. The CFX 4 was used to present successful solutions for the sloshing,overturning and re entry of hold water of the ship with large amplitude roll motion. Numerical investigations were carried out for the sloshing problems with various depth,roll amplitude of hold in forced or free oscillation.It was found that the water depth plays an important role in sloshing. The effect of shallow hold water is more important than that of the deep in some frequencies. |
