Abstract
This paper discusses the effects of wall properties on the peristaltic flow of an incompressible third grade fluid in a curved channel. Series solution is obtained under the approximation of long wavelength and low Reynolds number. Relation of stream function is derived. The variations of the interesting parameters entering into the problem are carefully analyzed. It is observed that the velocity profiles are not symmetric about the central line of the curved channel. Moreover, the bolus size increases with an increase in the curvature parameter in the upper half of the channel. Whereas it is found to decrease upon increasing the curvature parameter in the lower half of the channel.
