Solution of Time Periodic Electroosmosis Flow with Slip Boundary

Abstract and Applied Analysis, 2014
Recent research confirms that slip of a fluid on the solid surface occurs at micrometer scale. Slip on solid surface may cause the change of interior material deformation which consequently leads to the change of velocity profile and stress field.
