Abstract
Thermal radiation, thermal diffusion, and diffusion-thermo effects on heat and mass
transfer by mixed convection of non-Newtonian power-law fluids over a vertical permeable surface
embedded in a saturated porous medium are investigated. The governing equations describing the
problem are non-dimensionalized and transformed into a non-similar form. The transformed equations
are solved by using the local non-similarity method combined with the shooting technique.
The effects of the physical parameters of the problem on the fluid temperature and concentration
are illustrated graphically and analyzed. Also, the effects of the pertinent parameters on the local
Nusselt number and the local Sherwood number are presented.
