The Effects of Soret and Dufour on Mixed Convection Boundary Layer Flow of a Porous Media along a Permeable Surface filled with a Nanofluid and Radiation

Abstract

An investigation of mixed convection flow in a boundary layer saturated by a nanofluid and lodged in a porous medium with the existence of Soret and Dufour numbers, suction and thermal radiation is numerically studied. By employed a similarity transformation technique, the governing set of ordinary differential equations has been conducted from a non-linear partial differential equations system, where we apply a Runge-Kutta-Fehlberg method in order to numerically solved the final equations for a group of variety metallic and nonmetallic nanoparticles in a water base fluid consisting of copper (Cu), aluminium oxide (Al2O3) and titanium dioxide (TiO2). Numerous values of presented parameters such as thermal radiation coefficient, suction parameters, as well asDufour and Soret numbers are graphically presented and discussed on the dimensionless velocity, temperature and concentration distributions profiles.
