某体育中心体育馆屋盖风压分布的数值模拟

Numerical simulation of wind pressure distribution on the roof of athletics center stadium

对泉州市海峡体育中心体育馆屋盖风压分布进行了数值模拟,并将在75°和105°风向角下的结果与风洞实验进行比较,两者大体上基本吻合,并对其误差进行分析,随后给出了体育馆屋盖附近流场的规律性,数值模拟结果说明了数值模拟在大跨屋盖风工程中应用的可行性。

This paper is about the numerical simulation study of mean wind pressures on the large roof of Quanzhou central stadium. The com- parision of the distribution of wind pressures on the roof with the results of wind tunnel test in the 75° and 105° direction shows that they are consist with each other. Some rules of wind flow fields in the stadium and around the roof were also discussed briefly. The results in this paper verify the feasibility of numerical simulation of large roofs in wind engineering.
