Abstract
The Electrohydrodynamic conduction mechanism is investigated in non-Newtonian dielectric fluids described by the Oldroyd-B model. We examine flow patterns, oscillation amplitudes, force competition mode, and power-law spectral scaling accompanying oscillatory flow. Commensurability magnitudes of the elastic stress and Coulomb forces alter the convective mode, leading to discrepancies in the electroelastic instability paths. The kinetic and elastic energies of driving parameters are quantified, and five subregions found for flow patterns. Dynamic behavior is related to the strong electroconvective flow within the heterogeneous charge layers.
