摘要
针对模拟的真实海洋环境,研究实际海洋中随机的不规则多方向波及其与简单结构的相互作用问题。采用无奇异边界元法求解三维时域二阶Stokes多方向波浪绕射问题,在单向入射波的基础上,模拟了多方向波和单个结构的相互作用,且对适用于本文模型的去奇异距离参数做了简单分析,得出去奇异距离、多方向波作用下的二阶力与波数关系的结论,可供多方向非线性水动力相关问题的研究进行参考。
The paper aims to simulate the real ocean environment and study the random irregular multi-directional waves in the actual ocean and their interaction with simple structures.In this work,the three-dimensional time-domain second-order Stokes wave diffraction problem was solved using desingularized boundary integral equation method(DBIEM).The interaction between the multi-directional waves and the single upright cylinder was simulated based on unidirectional wave simulation by superposition method.A simple method was established for analysis of the desingularized distance parameters applicable to the model,deriving a conclusion of the relation between the second-order force and the wave number under the action of desingularized distance and multi-directional wave.Results can be used to guide studies on relevant problem of multi-directional nonlinear hydrodynamics.
