Achod Aradian, Elie Raphael, Pierre-Gilles de Gennes
We discuss the behaviour of a thin soap film facing a frame element: the pressure in the Plateau border around the frame is lower than the film pressure, and the film thins out ove…
Dissipation in Dynamics of a Moving Contact Line
Ramin Golestanian, Elie Raphael
The dynamics of the deformations of a moving contact line is studied assuming two different dissipation mechanisms. It is shown that the characteristic relaxation time for a deform…
