Turbulence-Induced Fluctuating Interfaces in Heterogeneously-Active Suspensions
Siddhartha Mukherjee, Kunal Kumar, Samriddhi Sankar Ray
We investigate the effects of heterogeneous (spatially varying) activity in a hydrodynamical model for dense bacterial suspensions, confining ourselves to experimentally realizable…

Fringe around a Beet Slice: Wetting-induced Dimple in a Thin Liquid Film
Zhengyang Liu, Kunal Kumar, Yicong Fu +3
When a slice of beet is placed on a plate with a thin layer of beet juice, one can observe a clear fringe around the beet, where the color is more translucent than the rest of the…

Onset of Intermittency and Multiscaling in Active Turbulence
Kolluru Venkata Kiran, Kunal Kumar, Anupam Gupta +2
Recent results suggest that highly active, chaotic, non-equilibrium states of living fluids might share much in common with high Reynolds number, inertial turbulence. We now show,…
