Abstract
This paper is devoted to an investigation of the influences of thermal radiation on an unsteady, mixed, convection boundary layer flow and the heat transfer over a vertical heated permeable stretching sheet embedded in a porous medium. Different models of the nanofluid based on different formulae for the thermal conductivity and the dynamic viscosity and their effects on the fluid flow and the heat transfer characteristics are discussed. Using the similarity transformation, we transform the governing equations into similarity, non-linear, ordinary differential equations which are solved by employing a numerical shooting technique with a fourth-order Runge-Kutta integration scheme. The obtained results are presented graphically, and the physical aspects of the problem are discussed.
