25.1 INTRODUCTION Understanding the flow behavior of particulate suspensions as well
as pneumatic and dry granular flows is important for such diverse applications as in-plant …

Numerous experimental investigations on the vertical transport of dense gas–solid
suspensions indicate that particles tend to segregate toward the tube wall. Although models …

Molecular-dynamics-like simulations are utilized to map regions of flow parameter space
where steady flows occur for monodisperse assemblies of inelastic, frictional spheres …

We examine the problem of determining the particle-phase velocity variance and rhe-ology
of sheared gas-solid suspensions at small Reynolds numbers and finite Stokes numbers …

Results of a numerical study of the dynamics of a collection of disks colliding inelastically in
a periodic two-dimensional enclosure are presented. The properties of this system, which is …

The paper presents a linear stability analysis of cohesionless granular materials during
rapid shear flow. The analysis is based on the governing equations developed in the kinetic …

Most models of sediment transport are based on the hypothesis of a weak interaction
between the fluid and the sediment phase, where the main flow is subjected to the mass and …

The linear stability of granular material in an unbounded uniform shear flow is considered.
Linearized equations of motion derived from kinetic theories are used to arrive at a linear …

Particle dynamic simulations were carried out to examine the effect of microstructure
formation on the stress tensor in a sheared granular material. Clusters, which form due to the …

A molecular-dynamic computer simulation is used to examine rapid granular flow in a
vertical channel. A two-dimensional event driven algorithm is used with periodic boundary …
