In this research paper, a numerical study has been done on the viscous fingering instability
for the air-glycerin system in the 2D horizontal Hele-Shaw cell. The air and glycerin are …

Saffman–Taylor instability exhibits a stepwise unstable morphology from a stable interface to
viscous fingering, eventually leading to tip splitting. The nonlinear dynamics of the …

We demonstrate a novel instability found within unconfined viscous bands/rims, or free-
surface flows involving a longitudinal viscosity contrast. Such instabilities may be described …

In our previous study, we experimentally studied the effects of changes in the viscosity of the
displaced more-viscous liquid by instantaneous reactions on miscible viscous fingering …

We present experimental and theoretical results addressing the Reynolds number (Re)
dependence of drag reduction by sufficiently large concentrations of rodlike polymers in …

The objective of this study was to examine the feasibility of improving the performance of
EOR polymers by adding surface modified silica nanoparticles (NP). The nano-polymer sols …

We consider meniscus instabilities in thin elastic layers perfectly adhered to, and confined
between, much stiffer bodies. When the free boundary associated with the meniscus of the …

We examine the transient displacement of viscoelastic fluids by a gas in straight cylindrical
tubes of finite length. For the simulation of the processes, the mixed finite element method is …

Scalable manufacturing of micro-and nanoscale textured surfaces from polymer composites
is desirable in many applications from drag reduction in ship applications to energy-efficient …

An experimental study of immiscible viscous fingering (VF), formed during the injection of
surfactant solutions into viscous oil in a radial Hele-Shaw cell, in which both fluids are …
