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…
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
Nadia Bihari Padhan, Rahul Pandit
The Cahn-Hilliard-Navier-Stokes (CHNS) partial differential equations (PDEs) provide a powerful framework for the study of the statistical mechanics and fluid dynamics of multiphas…
Emergent turbulence and coarsening arrest in active-spinner fluids
Biswajit Maji, Nadia Bihari Padhan, Rahul Pandit
We uncover activity-driven crossover from phase separation to a new turbulent state in a two-dimensional system of counter-rotating spinners. We study the statistical properties of…
Liquid-Droplet Coalescence: CNN-based Reconstruction of Flow Fields from Concentration Fields
Vasanth Kumar Babu, Nadia Bihari Padhan, Rahul Pandit
Liquid-droplet coalescence and the mergers of liquid lenses are problems of great practical and theoretical interest in fluid dynamics and the statistical mechanics of multi-phase…
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…
Novel turbulence and coarsening arrest in active-scalar fluids
Nadia Bihari Padhan, Kolluru Venkata Kiran, Rahul Pandit
We uncover a new type of turbulence -- activity-induced homogeneous and isotropic turbulence in a model that has been employed to investigate motility-induced phase separation (MIP…
Unveiling the Spatiotemporal Evolution of Liquid-Lens Coalescence: Self-Similarity, Vortex Quadrupoles, and Turbulence in a Three-Phase Fluid System
Nadia Bihari Padhan, Rahul Pandit
We demonstrate that the three-phase Cahn-Hilliard-Navier-Stokes (CHNS3) system provides a natural theoretical framework for studying liquid-lens coalescence, which has been investi…
Direct Numerical Simulations of Three-dimensional Magnetohydrodynamic Turbulence with Random, Power-law Forcing
Ganapati Sahoo, Nadia Bihari Padhan, Abhik Basu +1
We present pseudospectral direct-numerical-simulation (DNS) studies of the three-dimensional magnetohydrodynamic (MHD) equations (3DRFMHD) with a stochastic force that has zero mea…
