| 摘 要： | 本文根据准相似性理论，对渠道湍充场，采用奇阶截断和逐级逼近的方法，对连续性方程、平均运动方程和忽略三阶关联项的二阶脉动速度关联方程进行了求解，得到和实验结果吻合的平均速度，二阶脉动速度关联项和湍流微尺度的计算结果。

| Abstract: | Based on the pseudo-similarity theory of turbulence, the continuity equation, the mean motion equations and the equations of the second order velocity correlation with ignoring the third order velocity correlation terms in a channel flow are solved numerically by means of the sucessive approximation, and the results of mean velocity, second order velocity correlations and the turbulent micro-scale are derived. The analysis are well agree with the experimental results. |
