Trapping and escape of viscous fingers in a soft Hele-Shaw cell
Viscous flow in the narrow gap between a rigid plate and a confined elastic solid has been observed to ‘choke’ at high flow rates, due to the deforming solid making contact with the plate and sealing the gap. When the viscous flow is driven by injection of a gas bubble, the advancing meniscus is sus...
