How long do particles spend in vortical regions in turbulent flows?
Akshay Bhatnagar, Anupam Gupta, Dhrubaditya Mitra +2
We obtain the probability distribution functions (PDFs) of the time that a Lagrangian tracer or a heavy inertial particle spends in vortical or strain-dominated regions of a turbul…
A regularity criterion for solutions of the three-dimensional Cahn-Hilliard-Navier-Stokes equations and associated computations
John D. Gibbon, Nairita Pal, Anupam Gupta +1
We consider the 3D Cahn-Hilliard equations coupled to, and driven by, the forced, incompressible 3D Navier-Stokes equations. The combination, known as the Cahn-Hilliard-Navier-Stok…
Melting of a nonequilibrium vortex crystal in a fluid film with polymers : elastic versus fluid turbulence
Anupam Gupta, Rahul Pandit
We perform a direct numerical simulation (DNS) of the forced, incompressible two-dimensional Navier-Stokes equation coupled with the FENE-P equations for the polymer-conformation t…
