A pseudospectral method is described for solving the time-dependent Poisson-Nernst-Planck equations of electrokinetic flow when a spherical droplet is exposed to a uniform applied DC electric field. The method has been designed to accurately resolve the thin Debye layers that develop adjacent to the drop interface. It has also been validated against two reduced asymptotic models derived in the thin Debye layer limit, one for the electrophoresis of a surface-charge carrying bubble and a second for flow of a zero surface-charge two-phase drop.
