Radially Locked Sun-Ray Patterns in Autocatalytic Reaction-Diffusion-Advection Systems
Surya Narayan Maharana, Luka Negrojević, Alessandro Comolli +1
Traveling fronts ubiquitous in physics, chemistry, and biology are prone to transverse cellular deformations due to diffusive or convective instabilities. Here we show both theoret…

Well-posedness and Fingering Patterns in Reactive Porous Media Flow
Sahil Kundu, Surya Narayan Maharana, Manoranjan Mishra
The convection-diffusion-reaction system governing incompressible reactive fluids in porous media is studied, focusing on the \( A + B \to C \) reaction coupled with density-driven…

Existence and Uniqueness of Solution to Unsteady Darcy-Brinkman Problem with Korteweg Stress for Modelling Miscible Porous Media Flow
Sahil Kundu, Surya Narayan Maharana, Manoranjan Mishra
The work investigates a model that combines a convection-diffusion-reaction equation for solute concentration with an unsteady Darcy-Brinkman equation for the flow field, including…
