摘要

这项工作接近一个具有各种圆形屋檐的典型工业棚屋,在少数几篇关于它的论文中指出,这有利于结构安全抵御风的作用。由于文献忽略了这种建筑构型,因此采用四面体网格进行域离散,借助Ansys Workbench软件,通过CFD计算得到了外压系数。此外,对建筑物周围的边界层进行了建模,以提高数据捕获的准确性。采用RNG K-Epsilon模型,确定了紊流效应。结果表明,在最敏感的区域,压力系数降低,容易发生由屋顶风引起的事故。最后,利用给出的速度场可以测量流型。

Numerical Study on Wind Pressures Caused by the Variation of the Rounding Radii of the Industrial Shed Eaves
This work approached a typical industrial shed with varied rounded eaves, which is pointed out, in the few papers on it, as favorable to structural safety against the action of the winds. Since the literature has neglected this building configuration, the external pressure coefficients were obtained by CFD with the aid of the Ansys Workbench software, applying tetrahedral meshes in the domain discretization. Furthermore, the boundary layer around the building was modeled for greater accuracy in data capture. Using the RNG K-Epsilon model, were determined the turbulent flow effects. The results indicated a reduction in the pressure coefficients in the most sensitive regions and prone to accidents caused by wind on the roof. Finally, the flow pattern can be measured using the presented velocity fields.
