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…

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…
