Flow Over an Exponentially Stretching Porous Sheet with Cross-diffusion Effects and Convective Thermal Conditions

Abstract

This article investigates the influence of cross-diffusion on the viscous fluid flow over a porous sheet stretching exponentially by applying the convective thermal conditions. Velocity slip at the boundary is considered. The numerical solutions to the governing equations are evaluated using successive linearisation procedure and Chebyshev collocation method. It is observed from this study that the rate of heat transfer escalated with enhance in the Biot number and reduced with increase in dufour number. While, the rate of mass transfer from the sheet to the fluid reduced with increase in both soret and Biot numbers. Finally, the obtained results for rate of heat transfer are compared with the published results in the literature for special cases. The influence of the pertinent parameters on the physical quantities are displayed through graphs.
