| 摘 要： | 风载荷是海洋平台主要的设计载荷,常规的规范算法在结果上偏于保守。本文基于N-S方程(Navier-Stokes)方程对某自升式钻井平台进行了风载荷的数值分析,控制方程—RANS(Reyolds Averaged Navier-Stokes)和连续性方程使用有限体积法离散。在此基础上,对数值分析中湍流模型选择及网格划分方法进行了讨论,分别采用CFX及FLUNET软件对海洋平台整体及单个构件的风载荷和形状系数进行了研究。

| Abstract: | Wind load is the primary design load of the offshore installation, however, the results calculated according to MODU rules are conservative. Numerical analysis of wind load for jack-up unit is studied in this paper based on Navier-Stokes equation. The governing equations, which are Reynolds Averaged Navier-Stokes (RANS) and continuity equations, are discreted by finite volume method (FVM). The turbulence model selection and element meshing method in numerical study are studied in this paper. Besides, two computational fluid dynamics (CFD) softwares, which are CFX and FLUENT, are used to study the wind loads of jack-up unit and its components, together with the shape coefficient. |
