A Reynolds-like Criterion for the Onset of Universal Active Turbulence
Kunal Kumar, Sandip Sahoo, Kirti Kashyap +4
Beyond a critical Toner--Tu drive, bacterial turbulence exhibits universal statistics, including a parameter-independent energy spectrum . We show that the same…

Geometry, elasticity, and activity in the transport of self-propelled filaments in turbulence
Kunal Kumar, Aliv Sahoo, Rahul Kumar Singh +1
We investigate the transport of elastic active filaments in two-dimensional turbulence, focusing on how propulsion geometry and elasticity determine vortex trapping and transport.…
