Immiscible flows that involve radial displacements of shear-thinning or shear-thickening
fluids by a Newtonian fluid in a homogeneous porous medium are modeled numerically …

Two distinct effects that polymers exhibit are shear thinning and viscoelasticity. The shear
thinning effect is important as the polymers used in chemical enhanced oil recovery usually …

We experimentally study the effects of normal stress differences in the immiscible radial
viscous fingering instability in a Hele–Shaw cell. Dilute low molecular weight poly (ethylene …

Various processes are developed to fabricate meso and micro size fractal structures for wide
variety of engineering applications. Various types of fluid flows are studied and are deployed …

Abstract Development of meso and micro size fractal structures is required to mimic various
biological systems for various functions. Meso and micro size fractal structures are fabricated …

Miscible flow displacements in a rectilinear Hele‐Shaw cell of Newtonian as well as
rheologically well‐characterized shear‐thinning fluids are examined through experimental …

The displacement flow of an organic Newtonian fluid by a pure viscoelastic aqueous
solution is experimentally investigated inside a circular microchannel of 200 μm …

The study deals with linear analysis of the stability of the interface of a radially displaced
fluid (at a constant flow rate or pressure) in the Hele–Shaw cell. As distinct from other …

We present an analytical approach to the problem of predicting the finger width of a simple
fluid driving a non-Newtonian (power-law) fluid. Our analysis is based on the Wentzel …

The variation of the classical viscous fingering instability is studied numerically in this work.
An investigation of the viscous fingering phenomenon of immiscible displacement in the …
