We review the experimental synthesis of smooth and rough particles, characterization of
surface roughness, quantification of the pairwise and bulk friction coefficients, and their …

The increasing necessity of challenging wellbore structures and drilling optimization for
improved hole cuttings cleaning has been growing along time. As a result, operator …

In light of a warming climate, the complexity of the El Niño/Southern Oscillation (ENSO)
makes its prediction a challenge. In addition to various flavors of ENSO, oceanic warming in …

The packing and flow of aspherical frictional particles are studied using discrete element
simulations. Particles are superballs with shape| x| s+| y| s+| z| s= 1 that varies from sphere …

Production of morphology-controlled cement foams remains challenging, mainly due to
bubble stability issues during cement setting. The use of cement paste with high yield stress …

Despite their apparent simplicity, suspensions of hard spheres in a Newtonian fluid show
complex non-Newtonian behaviors and remain poorly understood. Recent works have …

The performance of a comminution and classification process depends on the design and
configuration of each process unit, the configuration of the plant, the design of the control …

Pressure-imposed rheometry is used to examine the influence of surface roughness on the
rheology of immersed and dry frictional spheres in the dense regime. The quasistatic value …

A wide range of thermoreversible gels are prepared by cooling down to ambient
temperature hot aqueous polymer solutions. During the sol-gel transition, such materials …

When dealing with unsaturated wet granular materials, a fundamental question is: What is
the effect of capillary cohesion on the bulk flow and yield behavior? We investigate the …
