Patterned plates mould the shape of yield-stress fluids in lifted Hele-Shaw cells.
Vis sammendrag
As fluids displace one another in lifted Hele-Shaw cells, complex fingering patterns can emerge. Our understanding of such fingering instabilities in complex materials, such as yield-stress fluids, is still in its fledgling stage. Here we experimentally consider the finger growth dynamics of a yield-stress fluid displaced by air in a lifted Hele-Shaw cell confined by various groove patterned plates. As air displaces the yield-stress fluid, the emergent fingering pattern depends on the lifting speed, initial plate separation and plate texture. Interestingly, we find that the plate’s texture influences finger growth, even outside the regime of traditional unstable viscous fingering, which will be discussed.

An experimental study of the interplay between viscous, capillary and gravitational forces in two-phase flow in a three-dimensional porous medium.
Vis sammendrag
We study the interplay between viscous, capillary and gravitational forces in two-phase flow in a threedimensional
porous medium, with the use of an optical scanner based on index-matched medium and fluorescent
fluids. A more viscous, denser, fluid is injected into a less viscous, less dense fluid in a 3D porous
medium, comprised of randomly packed glass beads of uniform size. We tune the injection rate over 10 experiments.
Experience from the 2D scenario suggests that with a slow injection rate capillary and gravitational
forces will dominate, and we should observe an unstable displacement and fingering. Conversely, with a high
injection rate, viscous forces will dominate, leading to a more stable displacement and a narrower invasion
front. How do the 2D findings hold up in the 3D scenario? We confirm the qualitative findings from the 2D
experiments and establish a clear regime change, from unstable to stable displacement. We seek to derive a
dimensionless number to quantify the relevant balance of forces and consider this number in relation to the
invasion pattern. We characterize the invasion by Minkowski-functionals and fractal dimensions and seek
relations between the found geometries and the derived dimensionless numbers.
