Examples
- Phenomenon of turbulent fluctuation
湍燎落现象 - In the results of eight 2d simulation cases with convective mach number ranged from 0 . 2 to 1 . 0 the mean velocities and the thickness growth rates are in good agreement with experimental results , but the turbulent fluctuation intensities are larger
对对流马赫数从0 . 2到1 . 0的混合层的二维数值研究表明，平均速度分布和扩张率与实验结果相符合，但湍流脉动强度偏大。 - The numerical results show that the flow - field structures and main features of the compressible mixing layer including the distribution of mean velocity , turbulent fluctuation intensities , reynolds stress and growth rates agree well with experimental and other numerical results
计算出的流场结构和主要的流动特征包括平均速度、湍流脉动强度和雷诺应力的分布以及混合层扩张率都同实验测量和其他时间发展数值模拟结果符合得很好。 - As the strong normal share of the wind , turbulent fluctuation is strengthened and the sands are raised up from the surface ground the wind speed in the atmosphere of the low level has a horizontal share and this pushes the sands in the atmosphere aggregate , so the visibility descend
近地面风速的垂直切变和地面热通量的加大，都可使使边界层湍流加强扬起地面沙尘。地面锋区附近风场的强水平切变，锋面垂直环流及锋后斜压转换的作用，将地面卷起的沙尘带到高空，爆发强沙尘暴。
