"Electrohydrodynamic Instabilities of Viscous Drops"

ABSTRACT


A classic result due to G.I.Taylor is that a weakly conducting drop bearing zero net charge placed in a uniform electric field adopts either a prolate or oblate spheroidal shape, the flow and shape being axisymmetrically aligned with the applied field. Here I overview some intriguing symmetry--breaking instabilities occurring in strong applied DC fields: Quincke rotation resulting in drop steady tilt or tumbling, and pattern formation on the surface of a particle-coated drop.

BRIEF ACADEMIC/EMPLOYMENT HISTORY

Petia Vlahovska received a PhD in chemical engineering from Yale and MS in chemistry from Sofia University (Bulgaria). She was a postdoctoral fellow in the Membrane Biophysics Lab at the Max Planck Institute of Colloids and Interfaces (Germany). She was a faculty at the Thayer School of Engineering at Dartmouth College and joined the School of Engineering of Brown University in Fall, 2010. Dr. Vlahovska is the recipient of NSF Career Award and was a David Crighton Fellow at DAMPT, the University of Cambridge (UK).
