Irreversiblity in Bacterial Turbulence: Insights from the Mean-Bacterial-Velocity Model
Kolluru Venkata Kiran, Anupam Gupta, Akhilesh Kumar Verma and +1
We use the mean-bacterial-velocity model to investigate the \textit{irreversibility} of two-dimensional (2D) \textit{bacterial turbulence} and to compare it with its 2D fluid-turbu…
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…
Conditional stability of particle alignment in finite-Reynolds-number channel flow
Anupam Gupta, Pascale Magaud, Christine Lafforgue +1
Finite-size neutrally buoyant particles in a channel flow are known to accumulate at specific equilibrium positions or spots in the channel cross-section if the flow inertia is fin…
Effect of polymer-stress diffusion in the numerical simulation of elastic turbulence
Anupam Gupta, Dario Vincenzi
Elastic turbulence is a chaotic regime that emerges in polymer solutions at low Reynolds numbers. A common way to ensure stability in numerical simulations of polymer solutions is…
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…
The statistical properties of spiral- and scroll-wave turbulence in cardiac tissue
K. V. Rajany, Anupam Gupta, Alexander V. Panfilov +1
Disorganized electrical activity in the heart leads to sudden cardiac death. To what extent can this electrical turbulence be viewed as classical fluid turbulence,which is an impor…
