When a reactive and miscible less-viscous liquid displaces a more-viscous liquid in a Hele-
Shaw cell, reactive miscible viscous fingering takes place. We succeed in showing …

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 have succeeded in experimentally investigating the effects of a moderate Damköhler
number, Da (defined as the ratio between a characteristic time of fluid motion and that of a …

We experimentally investigated the effects of a chemical reaction involving precipitation on
the miscible viscous fingering pattern formed in a Hele-Shaw cell. The precipitation …

An experimental study is performed to investigate the impact of fluid elasticity on miscible
viscous fingering. Rectilinear flow experiments are performed by displacing aqueous Boger …

A volume tracking method was developed to simulate time-dependent unstable viscous
fingering in a Hele-Shaw cell. The effect of finite viscosity ratio μ r between displacing and …

We present an experimental study of viscous fingering caused by the displacement of an oil
phase by non-Newtonian fluids such as Carbopol® 940 with and without surfactant (SDS) …

Miscible fingering in a Hele-Shaw cell is studied by means of Stokes simulations and linear
stability analysis. The two-dimensional simulations of miscible displacements in a gap …

Viscous fingering experiments were performed by injecting a liquid to radially displace a
much more viscous liquid in a Hele-Shaw cell consisting of two parallel closely-spaced …
