体育场内风流场和直缘主看台挑篷风压力分布的三维数值模拟

3D Numerical Simulation of Wind Flow Fields in a Stadium and Pressure Distribution on the Roof of Grand Canopy

利用世界先进的计算流体工程软件CFX5 3,对我国设计的约旦哈桑体育场[1] 及其西看台上的大悬臂挑篷零度风向风流场和压力系数分布进行数值模拟 ,并将结果与风洞试验比较 ,以说明计算风工程在实际应用中的可行性。

Adopting the robust commercial CFX5.3 software in the world,wind flow fields and pressure distribution on an overseas grandstand roof designed in China,are presented.The results are compared with the wind tunnel experiment to express the feasibility of engineering application for computational wind engineering.
