Sloshing in a Hele-Shaw cell: experiments and theory

François Gallaire, Benjamin Jérémy Dollet, Francesco Viola

The response of the free liquid surface in a Hele-Shaw cell subjected to a horizontal oscillation is investigated. We study the low-oscillation-amplitude regime and we show, by varying the fluid viscosity, nu, and the forcing frequency, omega, that the rat ...

From the free surface flow of a viscoelastic fluid towards the elastic deformation of a solid

Marco Picasso

The free surface flow of an Oldroyd-B viscoelastic fluid is considered, following A. Bonito, M. Picasso, and M. Laso (2006)[1]. When removing a term in the extra-stress constitutive relation, the description of an elastic incompressible solid is obtained, ...

Characterization of the velocity fields generated by flow initialization in the CFD simulation of multiphase flows

John Richard Thome, Mirco Magnini

Recent improvements in numerical algorithms for Eulerian-based CFD simulations of multiphase flows can now recover the exact balance between the pressure and surface tension terms within the momentum equation. This has led to the minimization of the so cal ...

Scaling laws for jets of single cavitation bubbles

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Outi Supponen, Marc Tinguely

Fast liquid jets, called micro-jets, are produced within cavitation bubbles experiencing an aspherical collapse. Here we review micro-jets of different origins, scales and appearances, and propose a unified framework to describe their dynamics by using an ...

Simulation of bubble expansion and collapse in the vicinity of a free surface

Mohamed Farhat, Outi Supponen

The present paper focuses on the numerical simulation of the interaction of laser-generated bubbles with a free surface, including comparison of the results with instances from high-speed videos of the experiment. The Volume Of Fluid method was employed fo ...

Critical inclination for absolute/convective instability transition in inverted falling films

Nicolas Igor Jacques Kofman

Liquid films flowing down the underside of inclined plates are subject to the interaction between the hydrodynamic and the Rayleigh-Taylor (R-T) instabilities causing a patterned and wavy topology at the free surface. The R-T instability results from the d ...

Rayleigh-Taylor instability under curved substrates: An optimal transient growth analysis

François Gallaire, Gioele Mariano Nicolò Balestra, Pierre-Thomas Paul Brun

We investigate the stability of thin viscous films coated on the inside of a horizontal cylindrical substrate. In such a case, gravity acts both as a stabilizing force through the progressive drainage of the film and as a destabilizing force prone to form ...

Beer tapping: dynamics of bubbles after impact

François Gallaire, Pierre-Thomas Paul Brun, Vladislav Mantic Lugo

Beer tapping is a well known prank where a bottle of beer is impacted from the top by a solid object, usually another bottle, leading to a sudden foam overflow. A description of the shock-driven bubble dynamics leading to foaming is presented based on an e ...
