| 摘 要： | 本文用时间步进和边界元法,对在静水中由静止开始作横荡运动的三维柱体的流体动力问题进行了数值模拟,并在日本大学作了相应的模型试验.在计算中,自由面采用拉格朗日网格,物面和自由面的交界点同时满足其边界条件,外边界用不给定方向的单波假定.数值计算结果和模型试验结果吻合较好.

| Abstract: | The time stepping algorithm and BEM were used together forthe simalation of the nonlinear sway motion of a 3D cylinder.A modeltest was carried out in Nihon University.In the calculation,the Lagrang-inn free surface condition was used.On the outer boundary,the simplewave assumption was used and the wave direction was determined onlyby the wave itsef.The numerical calculation results show good agreementwith those measured in the model test. |
