U-shaped disks in Stokes flow: Chiral sedimentation of a non-chiral particle
Christian Vaquero-Stainer, Tymoteusz Miara, Anne Juel +2
We study the sedimentation of U-shaped circular disks in the Stokes limit of vanishing inertia. We simulate the flow past such disks using a finite-element-based solution of the 3D…
Peeling fingers in an elastic Hele-Shaw channel
J. V. Fontana, C. Cuttle, D. Pihler-Puzovic +2
Using experiments and a depth-averaged numerical model, we study instabilities of two-phase flows in a Hele-Shaw channel with an elastic upper boundary and a non-uniform cross-sect…
Axisymmetric gas-liquid displacement flow under a confined elastic slab
Gunnar G. Peng, Callum Cuttle, Christopher W. MacMinn +1
A circular Hele-Shaw cell bounded by a volumetrically confined elastic solid can act as a fluidic fuse: during radially outward fluid flow, the solid deforms in response to the vis…
The propagation of air fingers into an elastic branching network
Haolin Li, Anne Juel, Finn Box +1
We study experimentally the propagation of an air finger through the Y-bifurcation of an elastic, liquid-filled Hele-Shaw channel, as a benchtop model of airway reopening. With cha…
The engulfment of aqueous droplets on perfectly wetting oil layers
Callum Cuttle, Alice B. Thompson, Draga Pihler-Puzović +1
Place a droplet of mineral oil on water and the oil will spread to cover the water surface in a thin film -- a phenomenon familiar to many, owing to the rainbow-faced puddles left…
Self-similar and disordered front propagation in a radial Hele-Shaw channel with time-varying cell depth
Christian Vaquero-Stainer, Matthias Heil, Anne Juel +1
The displacement of a viscous fluid by an air bubble in the narrow gap between two parallel plates can readily drive complex interfacial pattern formation known as viscous fingerin…
Dynamics of front propagation in a compliant channel
Callum Cuttle, Draga Pihler-Puzović, Anne Juel
Front-propagating systems provide some of the most fundamental physical examples of interfacial instability and pattern formation. However, their nonlinear dynamics are rarely addr…
Viscous fingering and dendritic growth under an elastic membrane
Lucie Ducloue, Andrew Hazel, Draga Pihler-Puzovic +1
We investigate the viscous fingering instability that arises when air is injected from the end of an oil-filled, compliant channel. We show that induced axial and transverse depth…
