| 摘 要： | 随着各类液货船的不断增加,晃荡现象在船舶与海洋工程领域引起了广泛的关注.文章从不可压粘性流体的N-S方程组出发,运用任意拉格朗日(ALE)有限元法对水平激励下的二维液体晃荡现象进行了数值模拟.首先通过计算值与解析解的比较,验证了数值方法的有效性,进而分析了激励振幅、激励频率对晃荡现象的影响,最后计算了作用于壁面上的力和力矩.

| Abstract: | As the size of the fluid contained cargo ship increases,the sloshing problem has attracted significant attention in the fields of naval architecture and ocean engineering.A two-dimensional liquid sloshing problem in rectangular container subjected to a horizontal excitation is simulated by the Arbitrary Lagrangian-Eulerian(ALE) finite element method in this paper.The behavior of the fluid is expressed by the incompressible viscous Navier-Stokes(N-S) equation and the continuity equation.Firstly,the numerical... |
