Abstract:
Optimal hydraulic section determines the maximum capacity of open channel, which plays a vital role in practical engineering. Based on our existing research, this paper focuses on the optimal hydraulic section of steady uniform flow in rectangular open channels. The results are as follow: (1) the optimal hydraulic section of steady uniform flow in rectangular open channels is concerned with Reynolds number and the width-depth ration. (2) For the laminar steady uniform flow in rectangular open channels, the optimal hydraulic section is the one when the width-depth ration is 5.8. (3) For the turbulent steady uniform flow in rectangular open channels, the optimal hydraulic section is influenced by Reynolds number and width-depth ration and the optimal hydraulic section of the flow with large Reynolds number is the one when the width-depth ration is 2.
