Abstract
An analysis has been carried out to investigate the influence of variable viscosity and thermal conductivity in the mixed convection three-dimensional flow of viscous fluid by an exponential stretching surface with heat transfer. Temperature distribution of the surface is also assumed to vary exponentially. The governing system is transformed into ordinary differential equations by appropriate transformations and non-similar solutions are computed. The effects of pertinent parameters on the flow field and heat transfer characteristics have been examined qualitatively through graphs and numerical values. Comparisons of the present work is shown with the existing previous results in the limiting sense.
•Unsteady three-dimensional mixed convection flow with exponential stretching surface is considered.•Effects of variable viscosity and thermal conductivity are taken into account.•Temperature profile shows increasing behavior for high values of small parameter ϵ.•Convergent of series solution is ensured graphically and numerically .
