Abstract
The influence of thermophoretic transport of Al₂O₃
nanoparticles on heat and mass trans- fer in
viscoelastic flow of oil-based nanofluid past porous exponentially stretching surface with
activation energy has been examined. Similarity technique was employed to transform the gov- erning
partial differential equations into a coupled fourth-order ordinary differential equations which
were reduced to a system of first-order ordinary differential equations and then solved
numerically using the fourth-order Runge-Kutta algorithm with a shooting method. The re-
sults for various controlling parameters were tabulated and graphically illustrated. It was found
that the thermophoretic transport of Al₂O₃ nanoparticles did not affect the rate of
flow and heat transfer at the surface but it affected the rate of mass transfer of
the nanofluid which decayed the solutal boundary layer thickness. This study also revealed that
activation energy retards the rate of mass transfer which causes a thickening of the solutal
boundary layer.
