On the selection of Saffman-Taylor fingers in a tapered Hele-Shaw cell
Dipa Ghosh, Satyajit Pramanik
We present an analytical study for predicting the finger width of the Saffman-Taylor finger in a tapered Hele-Shaw cell. We consider a rectilinear geometry with a constant depth gr…

HOC simulations of miscible viscous fingering of a finite slice: A new insight
Mijanur Rahaman, Jiten C. Kalita, Satyajit Pramanik
We investigate the dynamics of viscous fingering (VF) in miscible slices in homogeneous, isotropic porous media. The fluid flow is governed by incompressible Darcy's law, whereas t…
