风向频率
- 网络wind direction frequency;frequency of wind direction
风向频率-
运用风向频率加权（WDFW）方法，结合大气流动和污染物扩散的CFD模型进行数值模拟计算。
CFD numerical simulation coupling with the wind direction frequency weighted ( WDFW ) method was carried out based on the conditions that were measured .

分析了测风塔各高度风速日、年变化，风向频率年月变化。计算分析了测风塔不同高度平均风速、风功率密度、有效小时数等风能参数。
Analyses and computation are made of the wind energy parameters measured at the tower such as the daily and annual variation of wind speed , the monthly and annual variation of wind direction frequencies , the mean wind and wind power density , effective hours of wind speed , etc.
