Influence of Wind Sensor Location on Bridge Tower on Measurement Results

摘要

摘要: 为探讨桥塔上风传感器安装位置对测量结果的影响,以计算流体力学大型商用软件Fluent为平台,采用有限体积法对计算域进行离散,基于k-湍流模型研究了桥塔附近的风场特性.分析了不同来流风速、不同来流风向下桥塔附近风观测点的风速、风向变化规律,给出了相应的风速修正系数和风向角修正值.研究结果表明:桥塔对测量结果的影响较大,桥塔上风传感器的安装位置应经过优化确定.风传感器位于迎风侧时,风速比值在0.45~1.30之间波动;位于背风侧时,风速比值在0.05~1.25之间波动.风传感器较优的安装位置为离塔1.0倍特征尺寸以上,且与来流方向的夹角在(45.0~56.5)范围内.

Abstract: In order to investigate the effect of wind sensor location on measurement results, finite volume method (FVM) was adopted to discretize the computational domain by taking the commercial computational fluid dynamics (CFD) software Fluent as a platform, and the k- turbulence model was used to calculate the wind environment. The variation laws of wind speeds and wind directions at wind observation points near bridge tower under different inflow wind speeds and directions were analyzed, and the correction values of wind speed and wind angle were given. The research results indicate that bridge tower affects the measurement results of wind sensors obviously, and the locations of wind sensors should be optimized. Wind speed ratio fluctuates from 0.45 to 1.30 when wind sensors are located in the upstream, and it changes from 0.05 to 1.25 when they are located in the downstream. The optimum locations of wind sensors should be where they have more than 1.0 time the characteristic size away from bridge tower and the angle between their locations and inflow is in the range of (45.0 to 56.5).
