Research on Wind Field of Transmission Tower Under the Complex Terrain

摘要

In order to explore the influence of complex terrain on the wind field around the transmission tower, this paper numerically simulates the complex terrain of the location of the collapsed tower in Zhenjiang, China. Based on the Computational Fluid Dynamics method, the large eddy simulation turbulence model is built to solve the fluid domain, and the flow field distribution of complex terrain is analyzed. The results show that wind velocity suddenly increased at the location of the collapsed tower under the complex terrain, and the velocity is generally higher than the original gradient wind velocity. The sudden spurt in wind velocity caused by terrain cannot be ignored.
