Collective dynamics of active suspensions on curved viscous interfaces
Yuzhu Chen, Vishal P. Patil, David Saintillan
Self-propelled particles can navigate complex environments, including viscous fluid interfaces with curved geometries. In this work, we study the emergent dynamics of a suspension…

Electrohydrodynamic drift of a drop away from an insulating wall
Diptendu Sen, Mohammadhossein Firouznia, David Saintillan +1
An isolated charge-neutral drop suspended in an unbounded medium does not migrate in a uniform DC electric field. A nearby wall breaks the symmetry and causes the drop to drift tow…

Stokes flow of an evolving fluid film with arbitrary shape and topology
Cuncheng Zhu, David Saintillan, Albert Chern
The dynamics of evolving fluid films in the viscous Stokes limit is relevant to various applications, such as the modeling of lipid bilayers in cells. While the governing equations…
