First observation of turbulence-like state in dense algal suspensions
Prince Vibek Baruah, Nadia Bihari Padhan, Biswajit Maji +2
Active turbulence arises typically in systems ranging from microorganisms and biopolymers to synthetic colloids, where chaotic flows are closely associated with motile topological…
Obstacle-aware navigation of smart microswimmers in a turbulent flow
Vaishnavi Gajendragad, Akanksha Gupta, Nadia Bihari Padhan +1
Microswimmers in turbulent flows often navigate complex, heterogeneous, and obstacle-rich environments, where they exhibit intricate behaviors such as trapping at and escape from o…
Non-reciprocal Binary-fluid Turbulence
Biswajit Maji, Nadia Bihari Padhan, Axel Voigt +1
Although effective non-reciprocal interactions have been investigated in a variety of fields, their consequences have not been explored in hydrodynamical turbulence. We initiate su…
Vortex triplets, symmetry breaking, and emergent nonequilibrium plastic crystals in an active-spinner fluid
Biswajit Maji, Nadia Bihari Padhan, Rahul Pandit
The formation of patterns and exotic nonequilibrium steady states in active-fluid systems continues to pose challenging problems -- theoretical, numerical, and experimental -- for…
Interface-induced turbulence in viscous binary fluid mixtures
Nadia Bihari Padhan, Dario Vincenzi, Rahul Pandit
We demonstrate the existence of interface-induced turbulence, an emergent nonequilibrium statistically steady state (NESS) with spatiotemporal chaos, which is induced by interfacia…
Hyperuniformity in ternary fluid mixtures: the role of wetting and hydrodynamics
Nadia Bihari Padhan, Axel Voigt
Phase separation in multicomponent fluids is central to understanding the organization of complex materials and biological structures. The Cahn-Hilliard-Navier-Stokes (CHNS) equati…
