Abstract:
This dissertation describes the physics of granular particles in two different flow configuration:
Poiseuille and Taylor-Couette. In the first part, smooth inelastic disks are allowed to flow
under the effect of gravity in a two-dimensional channel. The particles are modeled as inelastic
hard particles which interact through binary collisions using event-driven molecular dynamics
simulations. In the second part, the particles are allowed to rotate in a cylindrical geometry
confined in the annular region between two cylinders, dubbed Taylor-Couette (TC) flow, with
inner cylinder rotating with different rotation rates in the absence of gravity.
