脉动速度 meaning in English
fluctuating velocity
fluctuation velocity
Examples
- The coefficients of skewness ( cs ) and kurtosis ( ce ) have the feature of cs < 0 , ce
纵向脉动速度概率密度分布的偏态系数0 0 ，峰态系数ce 。 - The correlation coefficient of velocity fluctuations - uv / u ' v " takes the shape of a reverse " c "
T颗粒两个方向脉动速度的相关系数一忑切’沿水深的分布呈一倒“ c ”形。 - The probability density distribution of the particle velocity fluctuation differs in different flow regions , and is approximately normally distributed where the space restrictions are small . velocity fluctuation of particles with different sizes is similar
颗粒脉动速度的概率密度分布随流区有所差异；在空间尺度影响较小的范围接近正态分布；各种粒径的颗粒脉动速度具有相似的特性。 - In the next part , after verifying the simplified computational method of turbulence , the movement of fibers in turbulent pipe flow was simulated by 3 - d integral method and simplified computational method of turbulence . it was found that the fluctuation of turbulence caused random of fibers " orientation and its distribution became broader as the re numbers increased
然后，在验证了湍流的简化方法的合理性后，利用三维分段计算方法和湍流简化方法模拟了大量纤维粒子在管道湍流内的运动，得出的结果为：湍流的脉动速度导致了纤维的偏角趋于无序，且随着re数的增加，纤维偏角的分布越来越趋于均匀。 - The motion characteristics of the suspended particles were obtained by statistical analysis , including vertical concentration distribution , mean velocity profile , turbulent intensity , velocity correlation , and the probability density distribution of the velocity fluctuations . attempt has also been made to interpret the turbulent characteristics in terms of particle properties and turbulence structure
