Magnetohydrodynamic peristaltic transport of Jeffrey nanofluid in an asymmetric channel

Abstract

In the present paper, the combined effects of magnetic field, buoyancy forces, thermophoresis and Brownian motion on the peristaltic flow of an incompressible Jeffrey nanofluid through an asymmetric channel have been studied under the long wavelength and low Reynolds number approximation. The resultant dimensionless nonlinear governing equations have been tackled numerically using Runge-Kutta-Fehlberg integration scheme. The computed results for nanofluid velocity, temperature and concentration fields are utilized to determine the skin friction, Nusselt number and Sherwood number. Pertinent results are displayed graphically with respect to the effects of various thermophysical parameters and the physical aspects are discussed. It is found that both velocity and nanoparticles concentration decrease while the temperature increases with an increase in the strength of magnetic field. An increase in the phase angle also decreases the magnitude of the velocity.
