摘要
通过分析陡槽中紊流边界层特性,利用边界层理论中的内变量法直接求解边界层运动方程,导出边界层发展厚度的理论分析式。并与已有的实测结果、若干经验计算式做了比较。
Through analysis of the behaviors of the turbulent boundary layer on a steep slope channel or over a spillway , this paper solves the motion equations of the turbulent boundary layer by a law of wall and presents the theoretiecal formula for the turbulent boundary layer development thickness. Ascompared with experimental results and some of experimental formulas, the analytical results are reasonable.
