Worm Structure in Modified Swift-Hohenberg Equation for Electroconvection
, 1997 A theoretical model for studying pattern formation in electroconvection is proposed in the form of a modified Swift-Hohenberg equation. A localized state is found in two dimension, in agreement with the experimentally observed ``worm" state.

On two-dimensional finite amplitude electro-convection in a dielectric liquid induced by a strong unipolar injection [PDF]
, 2015 The hydrodynamic stability of a dielectric liquid subjected to strong unipolar injection is numerically investigated. We determined the linear criterion Tc (T being the electric Rayleigh number) and finite amplitude one Tf over a wide range of the ...

, 2012 Soft-mode turbulence (SMT) is the spatiotemporal chaos observed in homeotropically aligned nematic liquid crystals, where non-thermal fluctuations are induced by nonlinear coupling between the Nambu-Goldstone and convective modes.

A Predictive Model for Convective Flows Induced by Surface Reactivity Contrast [PDF]
, 2017 Concentration gradients in a fluid along a reactive surface due to contrast in surface reactivity generate convective flows. These flows result from contributions by electro and diffusio osmotic phenomena. In this study we have analyzed reactive patterns

Temporal response to harmonic driving in electroconvection
, 2011 The temporal evolution of the spatially periodic electroconvection (EC) patterns has been studied within the period of the driving ac voltage by monitoring the light intensity diffracted from the pattern.
