数值风洞模拟要想获得理想的计算精度,依赖计算人员的理论基础及其在具体操作中对各种重要因素的选择.针对这个问题,采用现行<建筑结构荷载规范>作为比较标准,运用FLUENT软件,以正方形平面封闭式房屋的风荷载体型系数的数值模拟为例,重点讨论了湍流模型对数值模拟结果的影响,为合理使用数值风洞方法提供参考.%The desired accuracy of the numerical wind tunnel is depend on the theoritieal basis of staff and the choices of various important factors. The existing "building structures norms" is used as a comparison standerd , utilized FLUENT software, researched the wind load simulation of the square planar closed house, discussed the influence of turbulence models, offer reference for the rational use of numerical wind tunnel.
