Effect of Thermal Radiation on Mixed Convection Boundary Layer Flow Embedded in a Porous Medium Saturated by a Nanofluid
The problem of thermal radiation existence on mixed convection boundary layer flow embedded in a porous medium saturated by a nanofluid isinvestigated. The governing partial differential equations are reduced to the ordinary differential equations using the similarity transformations, which are solved numerically by Runge-Kutta-Fehlberg method for three types of metallic and nonmetallic nanoparticles, namely copper (Cu), alumina (Al2O3) and titania (TiO2) in a water based fluid. A comparison is made between the previously published and the present results reveals excellent agreement. The skin friction coefficient, temperature gradient, velocity and temperature profiles are graphically presented and discussed.
