This paper is devoted to the study of the peristaltic flow of a magnetohydrodynamic Walters B fluid through porous medium in a vertical asymmetric channel with heat transfer. The flow is investigated in the wave frame of reference moving with constant velocity with the wave. The non-linear governing partial differential equations are solved using perturbation technique by taking wave number as a small parameter. The expressions for pressure difference and frictional forces are calculated using numerical integration. The graphs are plotted to discuss the variation of velocity, pressure gradient, temperature, heat transfer coefficient, pressure difference, frictional force and trapping for the different flow parameters. It is observed from our analysis that, the trapping bolus and pumping rate increases with increase of heat generation parameter. In all situations the behaviour of Hartmann number and Darcy number always opposite.
