An experimental investigation of the stability of the circular hydraulic jump

JWM Bush, JM Aristoff, AE Hosoi - Journal of Fluid Mechanics, 2006 - cambridge.org
We present the results of an experimental investigation of the striking flow structures that
may arise when a vertical jet of fluid impinges on a thin fluid layer overlying a horizontal …

Planar hydraulic jumps in thin film flow

M Dhar, G Das, PK Das - Journal of Fluid Mechanics, 2020 - cambridge.org
We reformulate shallow water theory to understand viscous shear induced natural hydraulic
jumps in channels slightly deviated from the horizontal. One of the interesting contributions …

A coherent composite approach for the continuous circular hydraulic jump and vortex structure

W Wang, A Baayoun, RE Khayat - Journal of Fluid Mechanics, 2023 - cambridge.org
We examine the structure of the continuous circular hydraulic jump and recirculation for a jet
impinging on a disk. We use a composite mean-field thin-film approach consisting of …

Steady circular hydraulic jump on a rotating disk

A Ipatova, KV Smirnov, EI Mogilevskiy - Journal of Fluid Mechanics, 2021 - cambridge.org
The paper deals with the steady axially symmetric flow of a viscous liquid layer over a
rotating disk. The liquid is fed near the axis of rotation and spreads due to inertia and the …

Constant Froude number in a circular hydraulic jump and its implication on the jump radius selection

A Duchesne, L Lebon, L Limat - Europhysics Letters, 2014 - iopscience.iop.org
The properties of a standard hydraulic jump depend critically on a Froude number Fr defined
as the ratio of the flow velocity to the gravity waves speed. In the case of a horizontal circular …

The characteristics of the circular hydraulic jump and vortex structure

W Wang, A Baayoun, RE Khayat - Journal of Fluid Mechanics, 2024 - cambridge.org
In an effort to capture the continuous hydraulic jump and flow structure for a jet impinging on
a disk, we recently proposed a composite mean-field thin-film approach consisting of …

Circular hydraulic jump on finite surfaces with capillary limit

B Mohajer, R Li - Physics of Fluids, 2015 - pubs.aip.org
A round liquid jet impinging on a circular disc with free edge generates a thin liquid film in
the center surrounded by a thick film. For low flow rates, the thick film is bounded by a stable …

The transient spread of a circular liquid jet and hydraulic jump formation

A Baayoun, RE Khayat, Y Wang - Journal of Fluid Mechanics, 2022 - cambridge.org
The transient flow of a circular liquid jet impinging on a horizontal disk, and the hydraulic
jump formation, are examined theoretically and numerically. The interplay between inertia …

The role of gravity in the prediction of the circular hydraulic jump radius for high-viscosity liquids

Y Wang, RE Khayat - Journal of Fluid Mechanics, 2019 - cambridge.org
The free-surface flow formed by a circular jet impinging on a stationary disk is analysed
theoretically. We develop a simple and coherent model to predict the location and height of …

Numerical study of circular hydraulic jump using volume-of-fluid method

M Passandideh-Fard, AR Teymourtash, M Khavari - 2011 - asmedigitalcollection.asme.org
When a vertical liquid jet impacts on a solid and horizontal surface, the liquid starts
spreading radially on the surface, until a sudden increase in the fluid height occurs and a …
