We have studied the splashing dynamics of water drops impacting granular layers. Depending on the drop kinetic energy, various shapes are observed for the resulting craters. Experimental parameters that have been considered are : the size of the mill

A fountain of droplets

Autor: Terwagne, D., Delon, G., Adami, N., Vandewalle, N., Caps, H., Dorbolo, S.

A vessel is plunged upside down into a pool of 50 cSt silicone oil. An air bell is then created. This bell is vertically shaken at 60 Hz that leads to the oscillation of the air/oil interface. The edges of the immersed vessel generate surface waves t

Antibubbles in a cyclone eyewall

Autor: Terwagne, D., Delon, G., Vandewalle, N., Caps, H., Dorbolo, S.

A negative bubble, coined antibubble, is composed by a thin air shell that is immersed in a soapy mixture. A large vortex is generated in the liquid using a mixer. An antibubble is then created close to the surface. The antibubble is fastly attracted

Faraday instability on a network

Autor: Delon, G., Terwagne, D., Vandewalle, N., Dorbolo, S., Caps, H.

Faraday waves are generated at the air/liquid interface inside an array of square cells. As the free surface inside each cell is destabilizing due to the oscillations, the shape of the free surface is drastically changing. Depending on the value of t

Relaxation of a dewetting contact line Part 1: A full-scale hydrodynamic calculation

Autor: Snoeijer, J. H., Andreotti, B., Delon, G., Fermigier, M.

Publikováno v: J. Fluid Mech. (2007), vol. 579, pp. 63-83

The relaxation of a dewetting contact line is investigated theoretically in the so-called "Landau-Levich" geometry in which a vertical solid plate is withdrawn from a bath of partially wetting liquid. The study is performed in the framework of lubric

Relaxation of a dewetting contact line Part 2: Experiments

Autor: Delon, G., Fermigier, M., Snoeijer, J. H., Andreotti, B.

The dynamics of receding contact lines is investigated experimentally through controlled perturbations of a meniscus in a dip coating experiment. We first characterize stationary menisci and their breakdown at the coating transition. It is then shown
