Effect of Deborah Number and Phase difference on Peristaltic MHD flow of a fourth grade fluid in an inclined asymmetric channel

In this paper, we studied the effect of Deborah number and phase difference on MHD peristaltic flow of a fourth grade fluid in an inclined asymmetric channel under the assumption of long wavelength. Series solutions of axial velocity and pressure gradient are given by using regular perturbation technique when Deborah number is small. Numerical computations have been performed for the pressure gradient and pressure. The effects of various emerging parameters on the pressure gradient and pressure rise are studied in detail through graphs.
