Unsteady three-dimensional mixed convection flow with variable viscosity and thermal conductivity

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.
