摘要
本文研究了粗糙床面明槽紊流阻力特性,得到了流动二维性的判别标准,并对粗糙对满宁系数n及谢才系数C的影响进行了讨论,结果表明在小尺度粗糙情况下,C、n值可视为常数。
In this paper, the flow resistance in a flume with rough bed was studied, and the criteria of the 2-dimensional flow were obtained. Moreover, the effects of bed roughness on Manning factor n and Chézy factor C were discussed, the experimental results indicated that n and C can be taken as constants under small-scale roughness case.
