摘要

以某复杂体型高层建筑为例，对其风荷载进行了刚性模型风洞试验研究，并基于Fluent6.1软件平台，将雷诺应力湍流模型（RSM）与非平衡壁面函数搭配使用，对其进行了计算流体动力学（CFD）数值模拟。结果表明:风洞试验与数值模拟2种方法相辅相成；该类高层的迎风面主要受正压作用，屋面、背风面以及侧面主要受负压作用，尤其转角处背风区域局部负压较大；在180°风向角下，该类高层体型本身提供的类似峡谷的风速放大效应显著。

Abstract

Taking a complexshaped highrise building as a case

the wind tunnel test with rigid model was carried out for wind load study. Meanwhile

with Fluent 6.1 software

the CFD numerical simulation had been performed with the RSM and the Nonequilibrium Wall Functions. It was found that the results of the two methods were in good agreement. There were mainly positive pressures on the windward surface and negative pressures on the roof

the leeward surface and the side. Especially

negative pressure was higher in the leeward region at the building corner. And at the wind angle of 180°

the wind speed amplification effect was remarkable which was similar to those of canyons.
