Abstract: Effects of compliant wall properties on the peristaltic flow of a non-Newtonian fluid in an asymmetric channel were investigated.The rheological characteristics were characterized by the constitutive equations of a power-law fluid.Long wavelength and low Reynolds number approximations were adopted in the presentation of mathematical developments.Exact solutions were established for the stream function and velocity.The streamlines pattern and trapping are given due attention.The salient features of the key parameters entering into the present flow are displayed and important conclusions have been pointed out.
