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 …

Integral methods for shallow free-surface flows with separation

S Watanabe, V Putkaradze, T Bohr - Journal of fluid mechanics, 2003 - cambridge.org
We study laminar thin film flows with large distortions of the free surface, using the method of
averaging across the flow. Two specific problems are studied: the circular hydraulic jump …

The interplay between gravity and centrifugal forces in the continuous circular hydraulic jump

A Baayoun, RE Khayat - Physics of Fluids, 2024 - pubs.aip.org
The flow of a thin film over a rotating disk is crucial in many industrial applications, such as
spin coating and jet cooling. Accurate prediction of hydrodynamic features is essential for …

Modulation of viscous planar jump by an obstacle in the flow path—Interrogation through shallow water equations and numerical analysis

M Dhar, S Ray, G Das, PK Das - Physics of Fluids, 2021 - pubs.aip.org
The paper investigates a planar hydraulic jump during a thin film flow over a two-
dimensional obstacle spanning the entire width of a horizontal channel. The shallow water …

Bifilm defect formation in hydraulic jump of liquid aluminum

FY Hsu - Metallurgical and Materials Transactions B, 2016 - Springer
In aluminum gravity casting, as liquid aluminum fell through a vertical sprue and impacted
on the horizontal flat surface, a phenomenon known as hydraulic jump (ie., flow transition …

Mode bifurcation by pouring water into a cup

H Kitahata, A Yamada, S Nakata - The Journal of chemical physics, 2003 - pubs.aip.org
Mode bifurcation was investigated when water was poured into a cup. Three modes, ie,
accumulation flow mode I, scattering flow mode II, and oscillatory flow mode III, were …
