Influence of heat and mass transfer on the peristaltic flow of a Johnson Segalman fluid in a vertical asymmetric channel with induced MHD

This article deals with the influence of heat and mass transfer on the peristaltic flow of a Johnson Segalman fluid with induced magnetic field. The two dimensional equations of Johnson Segalman fluid are simplified by making the assumptions of long wave length and low Reynolds number. The arising equations are solved by using three types of techniques namely the perturbation, homotopy analysis method and numerical technique Graphical results are sketched for various embedded parameters and interpreted.
