| 摘 要： | 以位于广州珠江新城CBD核心区的303m高利通广场超高层建筑为对象，基于Fluent平台模拟结构表面的风压分布，对比了不同湍流模型下的计算结果，并与刚性模型测压风洞试验结果进行了比对．研究结果表明，采用本研究的参数设置和求解方法可以得到与经典文献相同的风压分布规律；观察到了流场中气流分离、再附和尾涡等现象；模拟结果与风洞试验结果具有一致的趋势，最大模拟误差小于25％，位于尾流区的背风面和侧面；Realizable k-ε模型在气流分离区可以得到与风洞试验更加接近的结果．

| Abstract: | Wind pressure distribution on Leatop Plaza with height of 300 meters level in Zhujiang New Town, CBD of Guangzhou, is simulated on the platform of Fluent. Results under different turbulent models are compared with wind tunnel tests. Studies show that wind pressure distribution consistent with the classical document can be achieved by the proposed parameter settings and solving method, and flow separating, reattachment and wake flow are observed. The numerical results agree well with experimental results, the maximum error is less than 25 %, locating on leeward and side surface. The Realizable k-ε turbulence model will produce more accurate results than other three models. |
