A coupled Eulerian Lagrangian approach for fluid and particle dynamics
Snehanshu Maiti, Rajaraman Ganesh
We present a one-way coupled Eulerian-Lagrangian computational framework for simulating fluid and particle dynamics in two-dimensional incompressible flows. The framework extends t…
Eulerian Lagrangian relations in decaying two dimensional incompressible Navier Stokes fluids across initial vorticity packing and Reynolds number
Snehanshu Maiti, Rajaraman Ganesh
Recent studies Vorticity packing effects on long time turbulent transport in decaying two dimensional incompressible Navier Stokes fluids, Phys. Fluids 38, 045159 (2026) demonstrat…
Numerical Study of Alfven Wave-Energetic Particle Interaction in the Inner Van Allen Belt and predictions of Seismic-Related Energetic Proton Bursts for the IITMSAT Mission
Snehanshu Maiti, Harishankar Ramachandran
The IIT Madras nano-satellite aims to investigate the science of energetic particle precipitation from the inner Van Allen radiation belt into the upper ionosphere as a potential p…
Vorticity Packing Effects on Long Time Turbulent Transport in Decaying Two-Dimensional Incompressible Navier-Stokes Fluids
Snehanshu Maiti, Shishir Biswas, Rajaraman Ganesh
Recent high-resolution, high-Reynolds-number simulations have shown that the initial total circulation, quantified by the vorticity packing fraction (VPF), strongly influences the…
A 3D Kinetic Distribution that Yields Observed Plasma Density in the Inner Van Allen Belt
Snehanshu Maiti, Harishankar Ramachandran
A steady-state distribution is obtained that approximately yields the observed plasma density profile of the inner Van Allen radiation belt. The model assumes a collisionless, magn…
