The flow deep within granular piles
Aqib Khan, Prabhu R Nott
Grain piles embody the complex mechanics and kinematics of disordered granular materials, including solid-like and fluid-like behaviours, complex kinematics, and preparation histor…
Analysis of the flow of granular materials through a screw conveyor
Aashish Kumar Gupta, Prabhu R. Nott
Screw conveyors are widely employed in industry for the bulk transport of particulate materials. Several studies have attempted to correlate the discharge rate with the rotation sp…
Coherent force chains in disordered granular materials emerge from a percolation of quasilinear clusters
K. P. Krishnaraj, Prabhu R Nott
Dense granular materials and other particle aggregates transmit stress in a manner that belies their microstructural disorder. A subset of the particle contact network is strikingl…
Stress relaxation in a dilute bacterial suspension: The active-passive transition
Sankalp Nambiar, Phanikanth S, Nott P. R. +1
We analyse the time dependent non-linear rheology of a dilute bacterial suspension (e.g. E. coli) for a pair of impulsively started linear flows - simple shear and uniaxial extensi…
The collective dynamics of self-propelled particles
Vishwajeet Mehandia, Prabhu R. Nott
We have proposed a method for the dynamic simulation of a collection of self-propelled particles in a viscous Newtonian fluid. We restrict attention to particles whose size and vel…
The statistics of particle velocities in dense granular flows
Sudheshna Moka, Prabhu R. Nott
We present measurements of the particle velocity distribution in the flow of granular material through vertical channels. Our study is confined to dense, slow flows where the mater…
