Control of radial miscible viscous fingering
Vandita Sharma, Sada Nand, Satyajit Pramanik +2
We investigate the stability of radial viscous fingering (VF) in miscible fluids. We show that the instability is decided by an interplay between advection and diffusion during ini…
A numerical study on reaction-induced radial fingering instability
Vandita Sharma, Satyajit Pramanik, Ching-Yao Chen +1
The dynamics of fronts is analyzed numerically in a radial geometry. We are interested to understand miscible fingering instabilities when the simple chemical…
Influence of Langmuir adsorption and viscous fingering on transport of finite size samples in porous media
Chinar Rana, Satyajit Pramanik, Michel Martin +2
We examine the transport in a homogeneous porous medium of a finite slice of a solute which adsorbs on the porous matrix following a Langmuir adsorption isotherm and can influence…
Confinement effects in premelting dynamics
Satyajit Pramanik, John S. Wettlaufer
We examine the effects of confinement on the dynamics of premelted films driven by thermomolecular pressure gradients. Our approach is to modify a well-studied setting in which the…
Viscosity scaling of fingering instability in finite slices with Korteweg stress
Satyajit Pramanik, Manoranjan Mishra
We perform linear stability analyses (LSA) and direct numerical simulations (DNS) to investigate the influence of the dynamic viscosity on viscous fingering (VF) instability in mis…
