Universality of shear-banding instability and crystallization in sheared granular fluid
Meheboob Alam, Priyanka Shukla, Stefan Luding
The linear stability analysis of an uniform shear flow of granular materials is revisited using several cases of a Navier-Stokes'-level constitutive model in which we incorporate t…
Hydrodynamic Theory for Reverse Brazil Nut Segregation and the Non-monotonic Ascension Dynamics
Meheboob Alam, Leonardo Trujillo, Hans J. Herrmann
Based on the Boltzmann-Enskog kinetic theory, we develop a hydrodynamic theory for the well known (reverse) Brazil nut segregation in a vibro-fluidized granular mixture. Using an a…
Orientational correlation and velocity distributions in uniform shear flow of a dilute granular gas
Bishakdatta Gayen, Meheboob Alam
Using particle simulations of the uniform shear flow of a rough dilute granular gas, we show that the translational and rotational velocities are strongly correlated in direction,…
Velocity Distribution and the Effect of Wall Roughness in Granular Poiseuille Flow
K. C. Vijayakumar, Meheboob Alam
From event-driven simulations of a gravity-driven channel flow of inelastic hard-disks, we show that the velocity distribution function remains close to a Gaussian for a wide range…
Universal Unfolding of Pitchfork Bifurcations and Shear-Band Formation in Rapid Granular Couette Flow
Meheboob Alam
A numerical bifurcation analysis is carried out to understand the role of gravity on the shear-band formation in rapid granular Couette flow. At {\it low} shear rates, there is a u…
First normal stress difference and crystallization in a dense sheared granular fluid
Meheboob Alam, Stefan Luding
The first normal stress difference () and the microstructure in a dense sheared granular fluid of smooth inelastic hard-disks are probed using event-driven simulati…
