| Summary: | 碩士 === 淡江大學 === 水資源及環境工程學系 === 86 === Dividing flow are of considerable importance in study of open-
channel. An experimental investigation of the flow structure at
a right angles dividing open-channel flow is presented. The most
comprehensive studies were concerned with backwater
characteristic and energy losses. Most of the investigators have
studied the problem depending on the control condition in the
main channel and thebranch channel. At present , the study of
dividing flow problem restricted thewidth ration of the branch
channel to the main channel 1.0 and 0.5. At thedownstream of the
branch channel, using a pump of 5 hp to pump. Result of this
study indicates that the section L0 and the section L4 has about
equal depth. In the branch channel, the width of circulation
zone is larger at the surface than at the bottom. The energy
loss is large in the branch channel due to circulation.
