The physics of granular flows is a fascinating subject because a range of complex collective
behaviour arise from seemingly simple microscopic interactions between the individual …

Experiments are conducted in a two-dimensional monolayer vibrofluidized bed of glass
beads, with a goal to understand the transition scenario and the underlying microstructure …

The nonlinear instability of the density-inverted granular Leidenfrost state and the resulting
convective motion in strongly shaken granular matter are analysed via a weakly nonlinear …

Three-dimensional molecular-dynamics simulations of cohesive dissipative powders under
a plane shear are performed. We find the various phases depending on the dimensionless …

The continuum deformation of gravity-driven dense granular materials on steep inclined
planes exhibit similar flow phenomenon to natural and industrial occurrences. This kind of …

The effects of three-dimensional (3D) perturbations, having wave-like modulations along
both the streamwise and spanwise/vorticity directions, on the nonlinear states of five types of …

The main objective of this work is to demonstrate that non-local terms of the structure
variable and shear-stress is a sufficient condition to predict multiple bands in rheologically …

In this thesis, we numerically and theoretically study the transport phenomena of cohesive
granular particles. First, we study spatial patterns of cohesive granular gases under a plane …

The subject of this thesis is the dynamics of granular materials. Granular matter is defined as
collections of macroscopic, dissipative particles. The size of the individual particles (grains) …

In micro-structural fluids, the homogeneous shear flow breaks into alternate regions of low
and high shear rates (ie, shear localization), respectively, when the applied shear rate …
