We study experimentally the stability of the interface between two shearing granular flows. Both flows consist of monosized spherical glass beads but they differ in particle size. When running on an inclined rough plane, the two flows reach different

International audience; An intriguing feature of granular matter is the close coexistence of solid-like regions and liquid-like flows. We study steady, fully-developped, granular flows confined between parallel vertical sidewalls. The sidewall fricti

1/falpha noise in the fluctuations of the spectra of tridiagonal random matrices from the beta-Hermite ensemble

Autor: C, Male, G, Le Caër, R, Delannay

Publikováno v: Physical review. E, Statistical, nonlinear, and soft matter physics. 76(4 Pt 1)

The 1/falpha noise displayed by the fluctuation of the n th unfolded eigenvalue, where n plays the role of a discrete time, was recently characterized for the classical Gaussian ensembles of NxN random matrices. It is investigated here for the beta-H

Study of Experimental and Simulated Evolutions of 2D Foams

Autor: V. Parfait-Pignol, A. Mocellin, R. Delannay

Publikováno v: Foams and Emulsions ISBN: 9789048151806

We study the effect of parameters such as the system size on the evolution of soap froth and cellular structures. Experiments show a significant effect of the size and the composition of the foaming liquid. Simulations based on Telley’s model (Lagu
