| 摘 要： | 液舱大幅晃荡一直是船舶水动力学研究的热点问题.文章采用Youngs法重构自由表面,给出了自由表面单元的速度边界条件,并且对液体晃荡中出现的流体翻卷、破碎后出现的流体波面的锋-锋相遇的情况进行了分析和讨论.数值模拟结果表明,Youngs法结合适当的自由表面条件,能够较好地模拟液舱内大幅晃荡中出现的翻卷和破碎的现象.

| Abstract: | The study on large amplitude sloshing is a noticeable subject of ship hydrodynamics.In this paper, Youngs method is adopted to reconstruct the free surface and the velocity boundary conditions of free surface cells are described.The cases of free surface fronts encounter which occur when the fluid turning and breaking are discussed.The code is programmed and the numerical simulation of large amplitude sloshing is performed.The results show that the method and the free surface velocity conditions are effecti... |
