Phase-coexisting patterns, horizontal segregation and controlled convection in vertically vibrated binary granular mixtures
I. H. Ansari, N. Rivas, M. Alam
We report new patterns, consisting of coexistence of sub-harmonic/harmonic and asynchronous states [for example, a granular gas co-existing with (i) bouncing bed, (ii) undulatory s…
Revisiting ignited-quenched transition and the non-Newtonian rheology of a sheared dilute gas-solid suspension
Saikat Saha, Meheboob Alam
The hydrodynamics and rheology of a sheared dilute gas-solid suspension, consisting of inelastic hard-spheres suspended in a gas, are analysed using anisotropic Maxwellian as the s…
Pattern-transition, microstructure and dynamics in two-dimensional vibrofluidized granular bed
I. Ansari, M. Alam
Experiments are conducted in a two-dimensional mono-layer vibrofluidized bed of glass beads, with a goal to understand the transition scenario and the underlying microstructure and…
Variable-cell method for stress-controlled jamming of athermal, frictionless grains
Kyle C. Smith, Ishan Srivastava, Timothy S. Fisher +1
A new method is introduced to simulate jamming of polyhedral grains under controlled stress that incorporates global degrees of freedom through the metric tensor of a periodic cell…
Isostaticity of Constraints in Jammed Systems of Soft Frictionless Platonic Solids
Kyle C. Smith, Meheboob Alam, Timothy S. Fisher
The average number of constraints per particle in mechanically stable systems of Platonic solids (except cubes) approaches the isostatic limit at the jamming point…
Athermal jamming of soft frictionless Platonic solids
Kyle C. Smith, Meheboob Alam, Timothy S. Fisher
A mechanically-based structural optimization method is utilized to explore the phenomena of jamming for assemblies of frictionless Platonic solids. Systems of these regular convex…
