Active control of liquid film flows: beyond reduced-order models
Radu Cimpeanu, Susana N. Gomes, Demetrios T. Papageorgiou
The ability to robustly and efficiently control the dynamics of nonlinear systems lies at the heart of many current technological challenges, ranging from drug delivery systems to…
Using electric fields to induce patterning in leaky dielectric fluids in a rod-annular geometry
Qiming Wang, Demetrios T. Papageorgiou
The stability and axisymmetric deformation of two immiscible, viscous, perfect or leaky dielectric fluids confined in the annulus between two concentric cylinders are studied in th…
Kortweg de-Vries solitons on electrified liquid jets
Qiming Wang, Demetrios T. Papageorgiou, Jean-Marc Vanden-Broeck
The propagation of axisymmetric waves on the surface of a liquid jet under the action of a radial electric field is considered. The jet is assumed to be inviscid and perfectly cond…
Spontaneous onset of convection in a uniform phoretic channel
Sébastien Michelin, Simon Game, Eric Lauga +2
Phoretic mechanisms, whereby gradients of chemical solutes induce surface-driven flows, have recently been used to generate directed propulsion of patterned colloidal particles. Wh…
Instability and dripping of electrified liquid films flowing down inverted substrates
Ruben J Tomlin, Radu Cimpeanu, Demetrios T Papageorgiou
We consider the gravity-driven flow of a perfect dielectric, viscous, thin liquid film, wetting a flat substrate inclined at a non-zero angle to the horizontal. The dynamics of the…
Optimal control of thin liquid films and transverse mode effects
Ruben J. Tomlin, Susana N. Gomes, Grigorios A. Pavliotis +1
We consider the control of a three-dimensional thin liquid film on a flat substrate, inclined at a non-zero angle to the horizontal. Controls are applied via same-fluid blowing and…
