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…

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…
