Influence of Chemical Reaction on Mixed Convection of Non-Newtonian Fluids Along Non-isothermal Horizontal Surface in Porous Media

The effect of chemical reaction on mixed convection heat and mass transfer in non-Newtonian fluid a long non-isothermal horizontal surface embedded in a saturated porous medium has been studied. The mixed convection regime is divided into two regions, namely, the forced convection dominated regime and the free convection dominated regime. The two solutions are matched. Numerical calculations are carried out for various values of dimensionless parameters and an analysis of the results obtained shows that the flow field is influenced appreciably by the chemical reaction, the buoyancy ratio, the viscosity index and the power-law of the wall temperature parameter. Effects of these parameters on the transport behaviors are investigated methodically and typically results are illustrated to reveal the tendency of the solutions. The results are presented graphically and the conclusion is drawn that the flow field and other quantities of physical interest are significantly influenced by these parameters.
