Slip effect on peristaltic transport of micropolar fluid

Abstract

In this paper, we investigate peristaltic transport of a micropolar fluid in a channel when no slip boundary condition is inadequate. The long wavelength and low Reynolds number approximations are used to get solution. The effects of coupling number, micropolar parameter and slip parameter on pumping region, friction force and trapping are analyzed and presented by graphs. It is found that the pumping region increases with increasing coupling number while it decreases with increasing micropolar parameter and slip parameter. The size of trapped bolus increases by increasing coupling number and micropolar parameter while it decreases by increasing slip parameter.
