摘　　要：应用目前可用于工程实践的、具有较高精确度和通用性的经典湍流模型———雷诺应力模型(RSM),进行了20多个涉及独立墙体、悬空广告牌、柱体和两个高层建筑静风荷载干扰效应流场的算例分析,并将计算结果与相关的风洞试验或现场实测结果进行了比较,从总体上阐述了两者间的异同,验证了数值风洞模拟结构静力风荷载的可行性.Using the common classical turbulence model, Reynolds stress equation model (RSM) which had fairly good precision and common usability, CFD simulations of more than twenty cases, including freestanding walls, elevated hoardings, square prisms and wind-induced static interference effects between two tall buildings, were conducted. Based on the comparison between the CFD and relative wind tunnel or field experimental data, essentially differences between them were depicted, and the feasibility of numerical wind tunnel in the simulation of static wind loads on buildings was verified.
