Flow in Open Channels, 3/e 6.1.1 Introduction. In considering unsteady flow in channels it is necessary to add time as a variable to the other combinations of hydraulic variables considered primarily in the first three chapters. By virtue of its free surface, uns... K Subramanya 被引量: ...
Channel expansions are common in both natural and engineered open channels. They connect a relatively narrow upstream section of channel with a large downstream section of channel. Due to increasing cross-sectional dimensions in an expansion, the flow decelerates. Under steady flow conditions flow dece...

In open channel flows, bottom and sidewall friction resistance can be neglected over a short transition1 as a first approximation. But the approximation of frictionless flow is no longer valid for long channels. Considering a water supply canal extending over several kilometres, the bottom and sidew...

Open Channel Flow Resistance 来自 Semantic Scholar 喜欢 0 阅读量: 176 作者: BC Yen 摘要: In 1965, Rouse critically reviewed hydraulic resistance in open channels on the basis of fluid mechanics. He pointed out the effects of cross-sectional shape, boundary nonuniformity, and flow unsteadiness, ...
LDA has been used in experimental research to define the time mean and turbulent flow of open channels, terrestrial canopies, overland flows, and density currents. Numerous studies have employed LDA in hydraulic flumes to examine the initiation, transition, and turbulent flow structure over bedforms...

Since its inception by Darcy (in 1857) and Weisbach (in 1845), the now called Darcy-Weisbach equation for determining frictional losses in open channels (and pipes) is considered ‘standard’ provided its associated friction factor coefficient\(f=8{({u}_{\ast }/{U}_{b})}^{2}\)is kno...
