Arching in confined dry granular materials

Peralta-Fabi, R; Malaga, C; Rechtman, R (1999)

We discuss a simple model that applies to a random array of arbitrarily shaped grains, contained between rigid vertical walls, that predicts arching. That is, the pressure (or weight) of the column of grains saturates as ...
Mesoscopic constitutive relations for dilute polymer solutions

Malaga, C; Mandujano, F; Santamaria, I (2006)

A novel approach to the dynamics of dilute solutions of polymer molecules under flow conditions is proposed by applying the rules of mesoscopic nonequilibrium thermodynamics (MNET). The probability density describing the ...
On arching in dry granular materials

PeraltaFabi, R; Malaga, C; Rechtman, R (1997)

Arching is studied experimentally and theoretically in a quasi two dimensional system. A model based on a stochastic coupled map lattice is proposed to characterize arching in a vertical and planar stack of similar beads. ...
A rising bubble in a polymer solution

Malaga, C; Rallison, JM (2007)

We propose a boundary integral method to study the shape of a bubble rising under gravity in a dilute polymer solution. Constitutive properties are modelled using a FENE model [M.D. Chilcott, J.M. Rallison, J. Non-Newtonian ...
