On the oscillatory dynamics of a Saffman--Taylor finger with a bubble at its tip
Jack Lawless, Andrew L. Hazel, Anne Juel
The complex behaviour of air-liquid interfaces driven into Hele-Shaw channels at high speeds could arise from oscillatory dynamics; yet, both the physical and dynamical mechanisms…

Periodic dynamics in viscous fingering
Jack Lawless, Andrew L. Hazel, Anne Juel
The displacement of a viscous liquid by air in the narrow gap between two parallel plates - a Hele-Shaw channel - is an exemplar of complex pattern formation. Typically, bubbles or…
