摘要
本文基于Navier-Stokes方程,采用CFD仿真分析软件对Spar平台上部模块的外流场进行了数值风洞模拟。选用三维稳态隐式解法,通过二阶迎风格式对控制方程进行离散,压力和速度耦合采用SIMPLE算法,针对不同风向和不同风速的工况组合,得到了Spar平台整体所受的风载荷,并与采用经验公式计算该平台的风载荷进行了对比分析。
Based on Navier-Stokes equation, CFD software is used in the numerical wind tunnel simulation of the upper Spar platform module by three dimensional static implicit methods. The second order upwind scheme is used to discretize the governing equations, and SIMPLE algorithm is used in pressure and speed coupling. The wind loads are obtained under different direction and velocities. Finally, comparison is made between numerical results and empirical formula.
