Blistering occurs when a thin solid layer locally separates from an underlying substrate
through cracking of a bulk material, delamination of a composite material, or peeling of a …

Control and stabilization of viscous fingering of immiscible fluids impacts a wide variety of
pressure-driven multiphase flows. We report theoretical and experimental results on a time …

The classical model for studying one-phase Hele-Shaw flows is based on a highly nonlinear
moving boundary problem with the fluid velocity related to pressure gradients via a Darcy …

We study the viscous-fingering instability in a radial Hele-Shaw cell in which the top
boundary has been replaced by a thin elastic sheet. The introduction of wall elasticity delays …

Viscous fingering experiments in Hele-Shaw cells lead to striking pattern formations which
have been the subject of intense focus among the physics and applied mathematics …

When a more mobile fluid displaces another immiscible one in a porous medium, viscous
fingering propagates with a partial sweep, which hinders oil recovery and soil remedy. We …

In this paper, we investigate the stability of immiscible viscous fingering in Hele-Shaw cells
with spatially varying permeability, across a range of capillary numbers. We utilise a coupled …

ABSTRACT Lifting plate Hele-Shaw cell involves a high viscous fluid sandwiched between
two parallel plates. The low viscosity fluid (air) enters from the periphery when one of the …

The injection of fluid into the narrow liquid-filled gap between a rigid plate and an elastic
membrane drives a displacement flow that is controlled by the competition between elastic …

The capture of a soft spherical particle in a rectangular slit leads to a nonmonotonic pressure-
flow rate relation at low Reynolds number. Simulations reveal that the flow induced …
