Stability Results on Radial Porous Media and Hele-Shaw Flows with Variable Viscosity Between Two Moving Interfaces
Craig Gin, Prabir Daripa
We perform a linear stability analysis of three-layer radial porous media and Hele-Shaw flows with variable viscosity in the middle layer. A nonlinear change of variables results i…

Time-dependent injection strategies and interfacial stability in multi-layer Hele-Shaw and porous media flows
Craig Gin, Prabir Daripa
We study the stability of multi-layer radial flows in porous media within the Hele-Shaw model. We perform a linear stability analysis for radial flows consisting of an arbitrary nu…

On a three-layer Hele-Shaw model of enhanced oil recovery with a linear viscous profile
Prabir Daripa, Oscar Orellana, Rodrigo Meneses
We present a non-standard eigenvalue problem that arises in the linear stability of a three-layer Hele-Shaw model of enhanced oil recovery. A nonlinear transformation is introduced…
