AbstractThe MHD Peristaltic flow and nanofluid with Newtonian heating in asymmetric channel is considered. The governing coupled equations are constructed under long wavelength and low Reynold’s number approximation. The Newtonian heating is controlled by a dimensionless conjugate parameter, which varies between walls of channel. HPM solutions are evaluated for nano particle fraction and heat transfer, while exact solutions are computed for stream function and pressure gradient. The important findings in this study are the variation of the conjugate parameter for Newtonian heating γ, Hartman number M, thermophoresis parameter Nt and Brownian motion parameter Nb on pressure rise, nano particle fraction, heat transfer phenomena, pressure gradient and streamlines. The velocity field increases due to increase in M near the channel walls while velocity field decreases at the centre of the channel.
