Annular Electroconvection with Shear Typeset Using Revt E X

Abstract We report experiments on convection driven by a radial electrical force in suspended annular smectic A liquid crystal lms. In the absence of an externally imposed azimuthal shear, a stationary one-dimensional (1D) pattern consisting of symmetric vortex pairs is formed via a supercritical transition at the onset of convection. Shearing reduces the… CONTINUE READING
