Electroosmotic flow dipole: experimental observation and flow field patterning

27 Feb 2019 Paratore Federico Boyko Evgeniy Kaigala Govind V. Bercovici Moran

We experimentally demonstrate the phenomenon of electroosmotic dipole flow that occurs around a localized surface charge region under the application of an external electric field in a Hele-Shaw cell. We use localized deposition of polyelectrolytes to create well-controlled surface charge variations, and show that for a disk-shaped spot, the internal pressure distribution that arises, results in uniform flow within the spot and dipole flow around it...
