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…

A Statistical Analysis Towards Modelling the Fluctuating Torque on Particles in Particle-laden Turbulent Shear Flow
Swagnik Ghosh, Partha Sarathi Goswami
Dynamics of the particle phase in a particle laden turbulent flow is highly influenced by the fluctuating velocity and vorticity field of the fluid phase. The present work mainly f…

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…
