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…
Nonmodal stability analysis of miscible viscous fingering with non-monotonic viscosity profiles
Tapan Kumar Hota, Manoranjan Mishra
A non-modal linear stability analysis (NMA) of the miscible viscous fingering in a porous medium is studied for a toy model of non-monotonic viscosity variation. The onset of insta…
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…
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…
