Symmetry-Constrained Exact Coherent Structures in Plane Poiseuille Flow
Akshit Nanda, Ritabrata Thakur
Turbulence in wall-bounded shear flows is increasingly understood through exact coherent structures (ECS) -- invariant solutions of the Navier-Stokes equations that act as organisi…

Viscosity variation in fluid flows across scale
Arjun Sharma, Ritabrata Thakur, Sharath Jose +1
A wide range of natural and engineered fluid flows exhibit spatial or temporal viscosity variations, spanning scales from microbial locomotion to planetary mantle convection. These…
