风压角

Factors affecting wind deflection caused discharge include wind speed, wind pressure ununiformity coefficient ,induded angle between wind and conductor,and transmission line parameters,etc.

风偏放电的影响因素有风速、风压不均匀系数、风与导线夹角、输电线路的参数等，通过对这些因素的逐一分析，明确了风速、风压不均匀系数和垂直档距对绝缘子风偏角影响较大。

And then, for 3D model, the wind speed and wind pressure distributing of single hill with diverse slope is researched. Based on it, the principle and process of narrow channels effect forming is showed visually and the change of airflow field in the valley and out of the valley under different wind angle is studied.

然后在三维情况下，探讨不同坡度的孤立山丘周围风速场和风压场的分布，在此基础上对山谷狭道效应的形成机理和过程做了直观的分析，并研究了不同风向角情况下峡谷内外风场的变化情况。

Comparisons between the results from the wind tunnel tests, numerical simulations and the field tests were performed to verify the accuracy of the CFD method. Then the advanced k-ε turbulence model was used to compute the mean pressures on a long span curve shaped roof with the front door open or not open.

在核实了数值模拟精度的基础上，运用改进的k-ε湍流模型对某曲面大跨网壳在大门开启和大门关闭两种不同工况下内、外表面的平均风压进行数值模拟研究，并考察了来流风向角和背景建筑对其风压分布的影响。
