Combined heat and mass transfer on
mixed convection non-similar flow of electrically conducting nanofluid along a
permeable vertical plate in the presence of thermal radiation is investigated.
The governing partial differential equations of the problem are transformed
into a system of non linear ordinary differential equations by applying the
Sparrow–Quack–Boerner local non-similarity method (LNM). Furthermore, the
obtained equations are solved numerically by employing the Fourth or fifth
order Runge Kutta Fehlberg method with conjunction to shooting technique.
The
profiles of flow and heat transfer are verified by using five types of nanofluids
of which metallic or nonmetallic nanoparticles, namely Copper (Cu), Alumina
(Al2O3), Copper oxide (CuO), silver (Ag) and Titanium (TiO2) with a water-based
fluid. Rosseland approximation model on black body is used to represent the
radiative heat transfer. Effects of thermal radiation, buoyancy force
parameters and volume fraction of nanofluid on the velocity and temperature
profiles in the presence of suction/injection are depicted graphically.
Comparisons with previously published works are performed, and excellentagreement between the results is obtained. The conclusion is that the flow
fields is affected by these parameters.
