Gas compression systematically delays the onset of viscous fingering
Liam C. Morrow, Callum Cuttle, Christopher W. MacMinn
Using gas to drive liquid from a Hele-Shaw cell leads to classical viscous fingering. Strategies for suppressing fingering have received substantial attention. For steady injection…
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…
Compression-driven viscous fingering in a radial Hele-Shaw cell
Callum Cuttle, Liam C. Morrow, Christopher W. MacMinn
The displacement of a viscous liquid by a gas within a Hele-Shaw cell is a classical problem. The gas-liquid interface is hydrodynamically unstable, forming striking finger-like pa…
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…
Dynamics of compression-driven gas-liquid displacement in a capillary tube
Callum Cuttle, Christopher W. MacMinn
We study two-phase displacement via the steady compression of an air reservoir connected to an oil-filled capillary tube. Our experiments and modelling reveal complex displacement…
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…
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…
