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…
Linear stability, transient energy growth and the role of viscosity stratification in compressible plane Couette flow
M. Malik, J. Dey, Meheboob Alam
Linear stability and the non-modal transient energy growth in compressible plane Couette flow are investigated for two prototype mean flows: (a) the {\it uniform shear} flow with c…
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…
Effects of Prandtl number and a new instability mode in a plane thermal plume
R. Lakkaraju, Meheboob Alam
The effect of Prandtl number on the linear stability of a plane thermal plume is analyzed under quasi-parallel approximation. At large Prandtl numbers (), we found that the…
