In order to get inspiration and find solutions to human issues, bio-mimicking is the act of
mimicking the diverse patterns, models, and systems of nature. The human body's veins …

We experimentally study the Saffman–Taylor instability of air invasion into a non-Newtonian
fluid (ie, Carbopol solution) in a rectangular Hele-Shaw cell. In addition to viscous features …

We propose a continuum model of two-phase flow in a Hele-Shaw cell. The model describes
the multiphase three-dimensional flow in the cell gap using gap-averaged quantities such as …

We study the fingering instabilities that occur in the debonding of model adhesives. We
perform a linear analysis of the instability in the lifting Hele-Shaw cell, relevant for the failure …

We study viscous fingering during drainage experiments in linear Hele-Shaw cells filled with
a random porous medium. The central zone of the cell is found to be statistically more …

Spreading on the free surface of a complex fluid is ubiquitous in nature and industry, such as
drug delivery, oil spill, and surface treatment with patterns. Here, we report on a fingering …

We experimentally study the viscous fingering problem of viscoplastic fluids in channels of
rectangular cross section. We find that a yield stress-dependent capillary number (Ca*) and …

Viscous fingering—the fluid-mechanical instability that takes place when a low-viscosity fluid
displaces a high-viscosity fluid—has traditionally been studied under either fully miscible or …

We study the injection of air into a granular suspension in a confined geometry. The grains
and the suspending fluid are density matched allowing to vary the grain fraction ϕ over the …
