Catheter-modulated transient solute dispersion in micropolar annular flow with a retentive and absorptive arterial wall
Sohel Ahmed, Nanda Poddar, Kajal Kumar Mondal +1
We study transient solute dispersion in pressure-driven micropolar flow through a concentric annulus representing a catheterized artery. The catheter is impermeable to solute, wher…

Solute dispersion in magnetically influenced multiphase flow through a porous tube: axial transport and microrotational effects
Sohel Ahmed, Nanda Poddar, Jyotirmoy Rana +2
This study presents a theoretical investigation of generalized solute dispersion in magnetohydrodynamic multiphase tube flow with porous layers. A two-fluid analytical model is dev…

Physics-informed neural networks for two-dimensional wall-reactive solute dispersion in canonical shear flows
Nanda Poddar, Subham Dhar
The dispersion of reactive solutes in shear flows is governed by the interplay between advective stretching, transverse diffusion, and boundary exchange kinetics. While classical a…
