摘要

本文基于欧拉多相流方法研究了输电塔表面的风雨荷载分布特性。首先基于现有某风驱雨实测模型建立CFD数值模型，基于欧拉多相流模型模拟获得结构表面雨滴抓取率，将模拟结果与现有实测数据进行对比，验证本文模拟结果的准确性。以某106.6 m高的钢管输电塔为例，基于输电塔结构特性将整塔沿高度分段，建立精细化输电塔CFD模型。采用SST

k‑ω

湍流模型模拟输电塔周围的流场，获得各塔段阻力系数，将模拟结果与现有规范进行对比验证风场模拟的准确性。雨相基于欧拉多相流通过Fluent的用户自定义函数（UDF）求解。选择合适的雨滴谱和雨滴粒径，求得不同粒径雨滴在计算域入口处的末速度和体积分数，模拟获得雨滴冲击壁面时的速度和体积分数，进而求得模型壁面抓取率和风驱雨荷载。结果表明：本模拟所得雨荷载与公式方法所得结果吻合较好，输电塔的风驱雨荷载随着降雨强度增大而增大。当降雨强度为709 mm/h时，输电塔各段顺风向雨荷载的最大值为风荷载的5.1%。

Abstract

In this study

the distribution characteristics of wind and rain loads on the surface of a transmission tower were investigated using the Euler multiphase flow method. First

the Computational Fluid Dynamics (CFD) numerical model was established based on an existing measured model of wind-driven rain

employing the Euler multiphase flow model to simulate the raindrop catch ratio on the structural surface. The simulation results were then compared with the existing measurement data to validate their accuracy. Taking a 106.6 m high steel pipe transmission tower as an example

the tower was segmented along its height based on structural characteristics to create a refined CFD model. The SST

turbulence model was adopted to simulate the flow field around the transmission tower

allowing for the calculation of drag coefficients for each tower section and enabling comparison with existing standards to confirm the accuracy of the wind field simulation. For the rain phase

the Euler multiphase flow method was implemented using a User Defined Function (UDF) in Fluent. Appropriate raindrop spectra and particle sizes were selected to determine the final velocity and volume fraction of different-sized raindrops at the

inlet of the computational domain. The simulation also captured the velocity and volume fractions of raindrops upon impact with the wall

allowing for the calculation of the wall catch ratio and wind-driven rain load. The results indicated that the simulated rain load aligned well with those obtained from formulaic methods

showing that the wind-driven rain load on the transmission tower increased with rainfall intensity. When the rainfall intensity was 709 mm/h

the maximum along-wind rain load for each section of the transmission tower reached 5.1% of the wind load.
