Abstract

Oceangoing ships may encounter rarely occurring waves like freak waves during their operational lifespan, which largely affects the safety of ships. In this paper a two-way CFD-FEM fluid-structure coupled method is adopted to simulate ship motions and wave load responses in three-dimensional (3D) freak waves. First, in-house code using MATLAB is developed to generate wave parameters which are used for generating short-crested waves and 3D freak waves in the CFD solver. The simulated freak waves are examined and the evolution of freak waves during propagation process is analyzed. Then, ship motions and wave loads considering hydroelastic response in 3D short-crested waves and in 3D freak waves are analyzed. The increase in motions and load responses when ship encountering freak waves is studied quantitatively. This study provides some insights into ship extreme dynamic responses in realistic seaways and in extreme freak waves.

异形波发生时三维现实海浪中船舶水弹性响应的数值模拟

远洋船舶在其使用寿命中可能会遇到罕见的异常浪，这在很大程度上影响了船舶的安全。本文采用双向CFD-FEM流固耦合方法，模拟了船舶在三维畸形波浪中的运动和波浪荷载响应。首先，利用MATLAB编写内部代码，生成CFD求解器中用于生成短峰波和三维畸形波的波参数。对模拟的畸形波进行了检验，分析了畸形波在传播过程中的演化。然后分析了三维短峰波和三维异形波中考虑水弹性响应的船舶运动和波浪荷载。定量研究了船舶遇异常浪时运动和载荷响应的增加。本文的研究为船舶在实际航道和极端异常浪中的极端动力响应提供了一些见解。

期刊介绍： The Journal of Fluids and Structures serves as a focal point and a forum for the exchange of ideas, for the many kinds of specialists and practitioners concerned with fluid–structure interactions and the dynamics of systems related thereto, in any field. One of its aims is to foster the cross–fertilization of ideas, methods and techniques in the various disciplines involved. The journal publishes papers that present original and significant contributions on all aspects of the mechanical interactions between fluids and solids, regardless of scale.
