| 摘 要： | 文章以深海平台为例,研究在迎浪海况的作用下,波浪对平台的砰击效应.将平台简化为大尺度,深吃水,几何形状规则的刚体,采用计算流体力学中的有限体积方法,将计算区域划分为一系列不重复的控制体积,使每个网格节点周围有一个控制体积,求解离散方程,利用流体体积理论捕捉自由表面的波形.依据三阶斯托克斯波波浪理论,利用fluent软件建立相应的数值水槽,并进行造波及消波设置,得到稳定的波浪场.采用固定平台六自由度的方法,初步地对平台所受的波浪砰击载荷进行分析计算.

| Abstract: | Taking one deep-water platform as an example, the slamming load on platforms in head-sea condition is analyzed. The platform is simplified as a rigid body with large size, deep draft, and regular geometry. The Finite Volume method of CFD is adopted to research this issue, which the computational range is divided into a series of control volumes to make each grid node surrounded by a control volume, and then the discrete equations can be solved. The waveform of free surface is monitored based on VOF Method. According to the third-orderStokes wave theory, a corresponding three dimensional numerical wave tank is built by the FLUENT, moreover, after the setting of wave-generating and wave-absorbing, stable wave environment is obtained. At last, the slamming load on the platform is calculated with the six degree of freedom of the platform fixed. |
