Wall-Wake Flows Downstream of a Sphere Placed on a Plane Rough Wall
The time-averaged characteristics of turbulent wall-wake flows downstream of a sphere placed on a rough wall are studied. The profiles of the defect of streamwise velocity, Reynolds shear stress, and…
Classical hydraulic jump: basic flow features
The dynamics of free surface flow is characterised by the so-called Froude number F, whose value F = 1 separates subcritical (F < 1) and supercritical (F > 1) flows. The transition from F < 1 to F >…
Scale effects of round-crested weir flow
ABSTRACT Scale effects of round-crested weir flow originate from viscosity and surface tension. No general weir flow equation accounting for these is available in the literature. In this work an…
Overflow characteristics of circular-crested weirs By SARA BAGHERI and MANOUCHEHR HEIDARPOUR, Journal of Hydraulic Research, Vol. 48, No. 4 (2010), pp. 515–520
The Discusser would like to congratulate the Authors for this interesting note, in which significant scale effects were observed for the discharge coefficient, yet no insight in scale effects of weir…
Subcritical Side-Weir Flow at High Lateral Discharge
Side weirs count among the important hydraulic structures for flow derivation in flood schemes or sewer networks. In this paper, the prismatic side weir in the rectangular channel is considered for…
Is the von Kármán constant affected by sediment suspension
[1] Is the von Karman constant affected by sediment suspension? The presence of suspended sediment in channels and fluvial streams has been known for decades to affect turbulence transfer mechanism…
Application of potential flow to circular-crested weir
The circular-crested weir is used for flow measurement and water level control in irrigation systems. It is also applied to flood and reservoir level control. In this study potential flow around the…
Spatially-varied open channel flow equations with vertical inertia
Spatially-varied open channel flows with a streamwise discharge variation occur in the side-weir, side-channel and bottom outlet. The governing equations were formulated in the 1970s by Yen and…
Energy and Momentum Velocity Coefficients for Calibrating Submerged Sluice Gates in Irrigation Canals
There is renewed interest in developing calibration methods for gates operating in submerged conditions in irrigation canals. In the present study, a new method based on a generalization of the…
