摘　　要：应用FLUENT软件的数值模拟方法,进行了单体建筑环境下的风效应仿真计算,模拟了单个建筑物的三维流场及表面风压系数,将数值模拟结果与实例风洞试验进行对比,验证了数值模拟分析结果的有效性和可行性,并在此基础上研究了风荷载环境的影响因素.According to the complexity of the surface environment,the diversity of building body,the wind flow around building usually has the disorder and irregular.It will lead to the complex and ever-changing series of studies that are difficult to predict.In this paper,FLUENT software was applied to carry out the numerical simulation of wind effects of single building and simulate the three-dimensional flow field and surface wind pressure coefficients of single building.The numerical simulation results were compar...
