Abstract
We investigate the electrically driven contact line dynamics of a binary fluid system constituted by one Newtonian and another non-Newtonian fluid in a narrow fluidic channel with chemically patched walls. We use a power-law model to describe the rheology of the non-Newtonian fluid and a diffuse interface phase-field method to model the dynamics of multiple phases. We bring out the alteration in the interfacial dynamics as attributable to the rheology-driven modifications in the interfacial stress and its interplay with the Maxwell stress originating from electrokinetic effects.
