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…

Hydrodynamics of Dense Active Fluids: Turbulence-Like States and the Role of Advected Activity
Sandip Sahoo, Siddhartha Mukherjee, Samriddhi Sankar Ray
Dense suspensions of self-propelled bacteria and related active fluids exhibit spontaneous flow generation, vortex formation, and spatiotemporally chaotic dynamics despite operatin…

Geometric Intermittency in Turbulence
Ritwik Mukherjee, Siddhartha Mukherjee, I. V. Kolokolov +3
Equal-time scaling exponents in fully developed turbulence typically exhibit non anomalous scaling in the inverse cascade of two-dimensional (2D) turbulence and anomalous scaling i…
