In this study the peristaltic motion of Oldroyd fluid in an asymmetric channel is investigated.
Mathematical analysis has been carried out in the presence of an inclined magnetic field. Heat transfer
is also taken into account. The physical problem is first modeled and then the analytical solutions of
coupled equations are developed by regular perturbation method. Assumptions of long wavelength
approximation are used. Effects of inclined magnetic field on the axial velocity and temperature are
presented. Physical features of pertinent parameters such as wave number δ, Reynolds number Re,
Weissenberg number Wi, Prandtl number Pr and Hartmann number M are also discussed graphically at
the end of the paper
