Soret and Dufour Effects in Three-Dimensional Flow of Jeffery Nanofluid in the Presence of Nonlinear Thermal Radiation

Abstract

The present research focuses on Soret and Dufour effects on three-dimensional flow of Jeffery nanofluid over a stretching sheet. The transport equation includes the effect of thermophoresis, Brownian motion of nano particles in the presence of nonlinear thermal radiation and uniform heat source/sink. Governing equations are transformed to ordinary differential equations and then solved numerically using Runge–Kutta–Fehlberg fourth–fifth order method with shooting technique. Computations are performed for various values of pertinent parameters against velocity, temperature and concentration profiles, which are depicted graphically along with some tabulated results on local Nusselt number and Sherwood number. It is observed that the nanoparticles concentration and associated boundary layer thickness are enhanced by increasing Soret and Dufour numbers. A comparison in a limiting sense is provided to validate the present solutions.
