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 …

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 …

The spread of a viscoelastic circular jet and hydraulic jump

A Baayoun, RE Khayat - The European Physical Journal Special Topics, 2024 - Springer
We examine theoretically the spread of a jet impacting on a circular disk and the hydraulic
jump of a viscoelastic fluid of the Oldroyd-B type. The depth-averaging approach is …

Low-order models for a circular hydraulic jump on a spherical cap

E Mogilevskiy, K Smirnov - Physics of Fluids, 2023 - pubs.aip.org
In this work, we analyze the flow of a thin layer of viscous liquid over the outer surface of a
sphere due to inertia and gravity. We use the classical problem of a circular hydraulic jump …

The viscoplastic circular hydraulic jump

W Wang, RE Khayat, JR de Bruyn - Physics of Fluids, 2023 - pubs.aip.org
We examine theoretically the spread of a jet impacting on a circular disk and the hydraulic
jump of a viscoplastic fluid of the Herschel–Bulkley type. The depth-averaging approach is …

Preventing sinking of a disk by leveraging the Parametric Hydraulic Jump phenomenon

J Turczynowicz, R Waszkiewicz, Ł Gładczuk - arXiv preprint arXiv …, 2023 - arxiv.org
Although it is commonly expected that a metal disk placed on the surface of water will sink,
our investigation has revealed a surprising phenomenon: a vertical jet directed onto the disk …
