Numerical simulations of viscoplastic fluid flows have provided a better understanding of
fundamental properties of yield stress fluids in many applications relevant to natural and …

We present a new continuum-based method for the realistic simulation of large-scale free-
flowing granular materials. We derive a compact model for the rheology of the material …

This paper proposes two regularized models of the μ (I)-rheology and shows their
application to the numerical simulation of 3D dense granular flows. The proposed …

We compare laboratory experiments, contact dynamics simulations and continuum Navier–
Stokes simulations with a. The dependency of the flow rate on the particle diameter is found …

The lubrication flow of a Herschel-Bulkley fluid in a symmetric long channel of varying width,
2h (x), is modeled extending the approach proposed by Fusi et al.[“Pressure-driven …

Granular intrusion is commonly observed in natural and human-made settings. Unlike
typical solids and fluids, granular media can simultaneously display fluid-like and solid-like …

So far, we have discussed the flowing behavior of passive granular matter, that is a medium
made of inert particles that are driven through interactions with other particles and …

A new brittle-elastoviscoplastic (BEVP) fluid model is presented in this paper. This model is
relatively simple to use, as it contains few material parameters and a simple fixed-point …

We studied experimentally the discharge of a vertical silo filled by spherical glass beads and
assisted by injection of air from the top at a constant flow rate, a situation which has practical …

In this work we propose to identify the relative role of the inclination of gravitational
acceleration and friction on the discharge flow rate of a granular media from a rectangular …
