输电塔平均风荷载数值模拟研究

Numerical simulation of mean wind force on transmission towers

对几个典型的输电塔试验模型所受的平均风荷载进行了CFD数值模拟,并将数值模拟结果与风洞试验结果进行对比,结果表明,基于Fluent的标准k—ε湍流模型对于格构塔式结构可以获得较好的数值模拟结果,利用CFD方法可以较好地模拟输电塔结构的平均风荷载。

In this paper, a numerical simulation on mean wind force is made. A comparison between the results of wind tunnel test and numerical simulation is made, and it shows that the k-ε turbulence model in Fluent can get good numerical simulation result on truss towers, and CFD could be an effective way to simulate the mean wind forces on transmission towers.
