Abstract
In this article free convective peristaltic motion of MHD Jeffrey nano fluid in an irregular channel is considered. Convective surface boundary conditions are incorporated for the thermal flow analysis. Energy equation exhibits the viscous dissipation. The problem prescribed under long wavelength and low Reynold's number approximation. HPM (homotopy perturbation method) is used to developed the solutions for nano particle fraction and heat transfer phenomena, while exact solutions are calculated for stream function and pressure gradient. The obtained results grip on “convection Biot number Bi, Hartmann number M, , Jeffrey fluid parameter λ, thermophoresis parameter Nt and Brownian motion parameter Nb”. The assets of different parameters on the flow quantities of observation are analyzed. As a concluding point, the streamlines are plotted and examined.
Keywords: Asymmetric channel, Convective boundary condition, Jeffrey nanofluid, Peristaltic flow.
