Analytical solution to problems of hydraulic jump in horizontal triangular channels

Ain Shams Engineering Journal, 2013
A hydraulic jump is formed in a channel whenever supercritical flow changes to subcritical flow in a short distance. It can be used in triangular ditch irrigation to raise the downstream water surface.

Turbulent shear stresses in hydraulic jumps, bores and decelerating surges [PDF]

, 2011
In an open channel, a sudden rise in water level induces a positive surge, or bore, that may develop as a hydraulic jump in translation. When the surge propagates against an adverse slope, it decelerates until it becomes a stationary hydraulic jump. Both

Development of the Bélanger Equation and Backwater Equation by Jean-Baptiste Bélanger (1828) [PDF]

, 2009
A hydraulic jump is the sudden transition from a high-velocity to a low-velocity open channel flow. The application of the momentum principle to the hydraulic jump is commonly called the Bélanger equation, but few know that Bélanger's (1828) treatise was

Theoretical Stable Hydraulic Section based on the Principle of Least Action

Scientific Reports, 2019
Despite decades of effort, stable hydraulic geometry for an open channel water flow has hardly been established because of too many unknown variables for too few rational relationships.

A-jump in horizontal inverted semicircular open channels

Ain Shams Engineering Journal, 2013
The hydraulic jump is a transitional state from supercritical to subcritical flow. The phenomenon of the hydraulic jump has been widely studied because of its frequent occurrence in nature and because of its uses in many practical applications.

Hydraulics of laminar open-channel flow

Journal of Hydraulic Research, 1986
The concepts of onedimensional flow and quasi-uniform flow are employed to derive the fundamental differential equation of gradually varied laminar flow in open channels.

The known unknowns of hydraulic engineering [PDF]

, 2008
Hydraulic engineers and researchers deal with scientific challenges involving turbulent flow motion and its interactions with the surroundings. Turbulent flows are characterised by unpredictable behaviour, and little systematic research has yet been ...
