Energy non-equipartition in vibrofluidized particles
Alok Tiwari, Manaswita Bose, V. Kumaran
The aim of the present work is to investigate the influence of the realistic model parameters for particle interactions, specifically the spring stiffness coefficient for the tange…
Dynamics of Particle-laden Turbulent Suspensions: Effect of particle roughness
S. Ghosh, P S Goswami, V. Kumaran
The Fluctuating Force Fluctuating Torque (F3T) model is developed and evaluated for the dynamics of a turbulent particle-gas suspension of rough spherical particles in a turbulent…
Stability of a high Mach number flow in a channel
M. Deka, G. Tomar, V. Kumaran
Modal instabilities in a flow through a channel at high Reynolds and Mach numbers are studied for three-dimensional perturbations. In addition to the Tollmien-Schlichting modes, th…
Moving efficiently through a crowd: a nature inspired traffic rule
Danny Raj M, Kumaran V
In this article, we propose a traffic rule inspired from nature, that facilitates an elite agent to move efficiently through a crowd of inert agents. When an object swims in a flui…
Turbulence collapses at a threshold particle loading in a dilute particle-gas suspension
V. Kumaran, P Muramalla, A. Tyagi +1
Two mechanisms are considered responsible for the turbulence modification due to suspended particles in a turbulent gas-particle suspension. Turbulence augmentation is due to the e…
Spontaneous phase separation in a vibro-fluidized granular layer
P Sunthar, V Kumaran
A new type of two phase coexistence in a vibrated granular material is reported, in the limit where energy transfer between the particles and the bottom wall occurs due to discrete…
