Non-Equal Width 75 degree Dividing Open Channel Flow
碩士 === 淡江大學 === 水資源及環境工程學系 === 89 === The study on non-equal width open-channel flow is using three kinds of channel width ratio(branch to main 1/1,1/2,1/3)and seven kinds of discharge ratio under 75 degree angles dividing flow by hydraulic experiments. The channel bed of present study is horizontal...

The channel bed of present study is horizontal and the cross section is rectangular.Beside this,the main channel flow is subcritical.At the downstream of main and branch channel use gates to control the flowrate and depth. The measurement including the depth and velocity of upstream and downstream in main and branch channel. According to the results of the experiment show that the flow angle will become smaller while the discharge ratio become larger. The different width of channel ratio,the flow angle will become larger while the width of channel become smaller. The width of circulation zone near water surface is larger than at the bottom.
