Abstract

In this paper, we have studied the influence of wall properties and aligned magnetic field on the peristaltic transport and heat and mass transfer of a Jeffrey/Newtonian nanofluid in a tapered channel. The analytical solutions are obtained for the stream function, the temperature and the concentration. Further, we obtained the Nusselt and Sherwood numbers at the wall. The effects of all important parameters on the physical quantities of the flow for both Jeffrey and Newtonian fluids are investigated through graphs and deliberated in detail. The velocity and temperatures are high for Newtonian fluid than Jeffrey fluid and the opposite situation is observed for concentration field. The large values of the magnetic parameter suppress the velocity and temperature fields but the reverse situation is seen in the case of concentration field. Also observed that the inclination angle of magnetic field and wall parameters have shown a significant effect on this investigation.
