Effect of Serum Starvation on Rheology of Cell Monolayers
Abhimanyu Kiran, Chandra Shekhar, Manigandan Sabapathy +4
The rheological properties of cells and tissues are central to embryonic development and homoeostasis in adult tissues and organs and are closely related to their physiological act…
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…
Stability of miscible Rayleigh-Taylor fingers in porous media with non-monotonic density profiles
Satyajit Pramanik, Manoranjan Mishra
We study miscible Rayleigh-Taylor (RT) fingering instability in two-dimensional homogeneous porous media, in which the fluid density varies non-monotonically as a function of the s…
Influence of viscosity contrast on buoyantly unstable miscible fluids in porous media
Satyajit Pramanik, Tapan Kumar Hota, Manoranjan Mishra
The influence of viscosity contrast on buoyantly unstable miscible fluids in a porous medium is investigated through a linear stability analysis (LSA) as well as direct numerical s…
Onset of fingering instability in a finite slice of adsorbed solute
Tapan Kumar Hota, Satayajit Pramanik, Manoranjan Mishra
The effect of a linear adsorption isotherm on the onset of fingering instability in a miscible displacement in the application of liquid chromatography, pollutant contamination in…
Non-modal linear stability analysis of miscible viscous fingering in porous media
Tapan Kumar Hota, Satyajit Pramanik, Manoranjan Mishra
The non-modal linear stability of miscible viscous fingering in a two dimensional homogeneous porous medium has been investigated. The linearized perturbed equations for Darcy's la…
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…
Effect of Péclet number on miscible rectilinear displacement in a Hele-Shaw cell
Satyajit Pramanik, Manoranjan Mishra
Influence of fluid dispersion on the Saffman-Taylor instability in miscible fluids has been investigated both in the linear and nonlinear regimes. The convective characteristic sca…
