Experimental study of Hydraulic Flow of Circular Piano-Key Inlet in Shaft Spillways
One of the most important conflicts that shaft spillways have to deal with is vortex formation. This phenomenon leads to some unfavorable effects such as vibration in the body of structures, air entrainment and reduced overflow capacity of the spillway. Among all solutions for disrupted vortex formation, an innovative one called circular piano-key spillway, based upon piano key weir principles ...

متن کاملEffect of Crest Roughness on Flow Characteristics over Circular Weirs
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures. In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...
متن کاملFlow Characteristics in a Rotating Circular Flume
Increased construction activity and associated receiving water concerns in the Greater Toronto Area has prompted this study to advance our knowledge on cohesive sediment transport processes in rivers and lake environments. Flow characteristics in a rotating circular flume at the National Water Research Institute (NWRI), Burlington, Ontario were studied using a computational fluid dynamics (CFD)...
متن کاملPredicting oxygen content downstream of weirs, spillways and waterways
P. Novak, Consultant In his paper the author has made a very useful contribution to the subject of prediction of oxygen content downstream of spillways, particularly in the case of surface aeration. However, some of the analysis referring to previously published results of oxygen uptake at hydraulic structures is not always rigorous enough. 40. The equations quoted for Avery and Novak apply to ...
