Beschreibung
Transitions may be broadly defined as that portion of a non-uniform channel undergoing a change in the normal prismatic section. In open channel and closed conduit flows, there are situations when the normal section of flow is to be restricted. In falls, Aqueducts, Siphons, Super-passages, Bridges, and Flumes and in many other similar hydraulic structures, the original section of flow is often reduced in order to economise the construction cost Transitions are useful for reducing loss in head and to ensure that the flow in the flumed section is smooth without any undue disturbances in flow upstream and downstream of transitions. In unlined canals, if suitable transitions are not provided, the vortices created at the entry and exit of the flumed section create not only head losses, it leads to flow non-uniformity resulting in non-uniform distribution of velocity and scouring which requires costly protective measures.The book covers transitions from sub-critical to sub-critical, sub-critical to supercritical, suprcritical to sub-critical and suprcritical to supercritical transitions.
