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…

Weakly nonlinear dynamics of a chemically active particle near the threshold for spontaneous motion. II. History-dependent motion
Gunnar G. Peng, Ory Schnitzer
We develop a reduced model for the slow unsteady dynamics of an isotropic chemically active particle near the threshold for spontaneous motion. Building on the steady theory develo…
