Rheology of dense granular suspensions (2018, methodology): “A simple model has been proposed by introducing the idea of a dilatancy angle, ψ (Pailha & Pouliquen 2009).”
A general two-phase debris flow model (2012, methodology): “…packing of spheres, d is particle diameter, hf is fluid viscosity, g = rf /rs is the density ratio, Rep ¼ rf dUT=hf is the particle Reynolds number [see, e.g., Pailha and Pouliquen, 2009], and assume that UT ¼ ffiffiffiffiffiffiffiffiffiffi gd=g p , which is an approximation for particle…”
The granular column collapse as a continuum: validity of a two-dimensional Navier–Stokes model with a μ(I)-rheology (2011, methodology): “The Gerris flow solver Gerris is an open-source solver for the solution of incompressible fluid motion using the finite-volume approach (Popinet 2003, 2009).”
