Innovations in fluid mechanics have been leading to better food since ancient history, while
creativity in cooking has inspired fundamental breakthroughs in science. This review …

Waterbells result from the impact of a low-viscosity liquid jet (diameter D 0, velocity U 0) on a
solid surface (characteristic length D i) of similar size (D i∼ D0). Their stationary shape …

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 …

We propose a theory of a steady circular hydraulic jump based on the shallow-water model
obtained from the depth-averaged Navier–Stokes equations. The flow structure both …

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 free-surface flow formed by a circular jet impinging on a rotating disk is analysed
theoretically. The study explores the effects of rotation and inertia on the thin-film flow. Both …

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 …

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 …

We propose a phenomenological model for the polygonal hydraulic jumps discovered by
Ellegaard and co-workers [Nature (London) 392, 767 (1998) NATUAS 0028-0836 …

Because of its high heat transfer potential, liquid jet impingement is broadly used in cooling
applications. As a free-surface jet spreads radially after impinging on a flat surface, a …
