风向频率加权
1.
A wind direction frequency weighted(WDFW) method based upon the atmosphere wind direction frequency characteristics,combining with solving the 3D Navier-Stokes equations,the mass and heat transfer equations as well as the standard k-ε turbulence models was proposed to model the local airflow and the dispersion of vehicular exhausted plume under real atmospheric conditions.
根据大气风向频率特征,提出风向频率加权(W DFW)方法,结合求解三维N-S方程、传热传质的对流扩散方程和k-ε湍流模型来预测实际大气条件下局地大气流动和污染物扩散规律,并与现场采样分析结果进行对比。

补充资料：风向标
| 风向标 wind vane 各种测风仪器中用以指示风向的最主要的部件。分为头部、水平杆和尾翼3部分。在风力的作用下，风向标绕铅直轴旋转，使风尾摆向下风方向，头部指向风的来向。风向标感应的风向必须传递到地面的指示仪表上，以电触点式最为简单，但一般只能作到每一个方位（22.5°）有一个触点。精确的方法有自整角机和光电码盘。 |
