Codimension-two points in annular electroconvection as a function of aspect ratio
V. B. Deyirmenjian, Zahir A. Daya, Stephen W. Morris
We rigorously derive from first principles the generic Landau amplitude equation that describes the primary bifurcation in electrically driven convection. Our model accurately repr…
Sequential Bifurcations in Sheared Annular Electroconvection
Zahir A. Daya, V. B. Deyirmenjian, Stephen W. Morris
A sequence of bifurcations is studied in a one-dimensional pattern forming system subject to the variation of two experimental control parameters: a dimensionless electrical forcin…
Electrically driven convection in a thin annular film undergoing circular Couette flow
Zahir A. Daya, V. B. Deyirmenjian, Stephen W. Morris
We investigate the linear stability of a thin, suspended, annular film of conducting fluid with a voltage difference applied between its inner and outer edges. For a sufficiently l…
Annular electroconvection with shear
Zahir A. Daya, V. B. Deyirmenjian, Stephen W. Morris +1
We report experiments on convection driven by a radial electrical force in suspended annular smectic A liquid crystal films. In the absence of an externally imposed azimuthal shear…
Weakly Nonlinear Analysis of Electroconvection in a Suspended Fluid Film
V. B. Deyirmenjian, Zahir A. Daya, Stephen W. Morris
It has been experimentally observed that weakly conducting suspended films of smectic liquid crystals undergo electroconvection when subjected to a large enough potential differenc…
