Single fiber transport by a fluid flow in a fracture with rough walls: influence of the fluid rheology
Maria Veronica D'Angelo, Harold Auradou, Guillemette Picard +2
The possible transport of fibers by fluid flow in fractures is investigated experimentally in transparent models using flexible polyester thread (mean diameter ) a…
Slow flows of yield stress fluids: complex spatio-temporal behaviour within a simple elasto-plastic model
Guillemette Picard, Armand Ajdari, Francois Lequeux +1
A minimal athermal model for the flow of dense disordered materials is proposed, based on two generic ingredients: local plastic events occuring above a microscopic yield stress, a…
Elastic consequences of a single plastic event : a step towards the microscopic modeling of the flow of yield stress fluids
Guillemette Picard, Armand Ajdari, Francois Lequeux +1
With the eventual aim of describing flowing elasto-plastic materials, we focus on the elementary brick of such a flow, a plastic event, and compute the long-range perturbation it e…
A simple model for heterogeneous flows of yield stress fluids
G. Picard, A. Ajdari, L. Bocquet +1
Various experiments evidence spatial heterogeneities in sheared yield stress fluids. To account for heterogeneities in the velocity gradient direction, we use a simple model corres…
The effect of forcing on the spatial structure and spectra of chaotically advected passive scalars
Zoltan Neufeld, Peter H. Haynes, Guillemette Picard
The stationary distribution of passive tracers chaotically advected by a two-dimensional large-scale flow is investigated. The tracer field is force by resetting the value of the t…
