Effect of different screen areas on the submerged hydraulic jump characteristics [PDF]

open access: yesPort Said Engineering Research Journal, 2022
The hydraulic jump is a natural phenomenon occurs in steep waterways and behind the heading up structures. The main benefit of the hydraulic jump is dissipating the excessive kinetic energy. Tools such as sill, baffle blocks… etc.

THE INFLUENCE OF OUTFLOW IN SUPERCRITICAL ACCRETION FLOWS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We solve the radiation-hydrodynamic equations of supercritical accretion flows in the presence of radiation force and outflow by using self-similar solutions. Similar to the pioneering works, in this paper we consider a power-law function for mass inflow rate as ...

Supercritical flow in circular conduit bends [PDF]

open access: yesJournal of Hydraulic Research, 2014
ABSTRACTA complex flow pattern occurring in a circular conduit bend with supercritical flow has been studied. The main objective was to obtain reliable criteria for prediction of the onset of helical and choking flow, in order to facilitate the design of bottom outlets, tunnel spillways and drainage collectors with bends.

Monitoring Scour at Bridge Piers in Rivers with Supercritical Flows

open access: yesHydrology, 2023
Bridges crossing rivers wider than 50 m are typically supported by piers. In a mobile riverbed, scour occurs around bridge piers, and it is the main cause of bridge collapses worldwide, especially during floods.

Supercritical flow at an abrupt drop: flow patterns and aeration [PDF]

open access: yesCanadian Journal of Civil Engineering, 1998
Stepped waterways and cascades are common features of storm waterways, at dam outlets, and in water treatment plants. At an abrupt drop, open channel flows are characterized by the presence of shock waves and a substantial flow aeration. There is, however, little information on the basic flow characteristics.
