Flocking of Active Particles in a Turbulent Flow
Anupam Gupta, Amal Roy, Arnab Saha +1
We investigate the effect of cooperative interactions in an ensemble of microorganisms, modelled as self-propelled disk-like and rod-like particles, in a three-dimensional turbulen…
Turbulent route to two-dimensional soft crystals
Mohit Gupta, Pinaki Chaudhuri, Jèrèmie Bec +1
We investigate the effects of a two-dimensional, incompressible, turbulent flow on mono-disperse soft granular particles and show the emergence of a crystalline phase due to the in…
Understanding droplet collisions through a model flow: Insights from a Burgers vortex
Lokahith Agasthya, Jason R. Picardo, S. Ravichandran +2
We investigate the role of intense vortical structures, similar to those in a turbulent flow, in enhancing collisions (and coalescences) which lead to the formation of large aggreg…
Flow structures govern particle collisions in turbulence
Jason R. Picardo, Lokahith Agasthya, Rama Govindarajan +1
The role of the spatial structure of a turbulent flow in enhancing particle collision rates in suspensions is an open question. We show and quantify, as a function of particle iner…
Preferential Sampling of Elastic Chains in Turbulent Flows
Jason R. Picardo, Dario Vincenzi, Nairita Pal +1
A string of tracers, interacting elastically, in a turbulent flow is shown to have a dramatically different behaviour when compared to the non-interacting case. In particular, such…
Inertial spheroids in homogeneous, isotropic turbulence
Amal Roy, Anupam Gupta, Samriddhi Sankar Ray
We study the rotational dynamics of {\it inertial} disks and rods in three-dimensional, homogeneous isotropic turbulence. In particular, we show how the alignment and the decorrela…
