Flow instabilities in complex fluids: Nonlinear rheology and slow relaxations
A. Aradian, M. E. Cates
We here present two simplified models aimed at describing the long-term, irregular behaviours observed in the rheological response of certain complex fluids, such as periodic oscil…
Surface flows of granular materials: A short introduction to some recent models
Achod Aradian, Elie Raphael, Pierre-Gilles de Gennes
We present a short review of recent theoretical descriptions of flows occuring at the surface of granular piles, and focus mainly on two models: the phenomenological ``BCRE'' model…
"Marginal pinching" in soap films
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…
Thick surface flows of granular materials: The effect of the velocity profile on the avalanche amplitude
Achod Aradian, Elie Raphael, Pierre-Gilles de Gennes
A few years ago, Bouchaud al. introduced a phenomenological model to describe surface flows of granular materials [J. Phys. Fr. I, 4, 1383 (1994)]. According to this model, one can…
