Double-diffusive convection flow in a porous medium saturated with a nanofluid.

In this work, we studied heat and mass transfer in a nanofluid flow over a stretching sheet.
Fluid flow in different flow geometries was studied and a co-ordinate transformation was
used to transform the governing equations into non-dimensional non-similar boundary layer
equations. These equations were then solved numerically using both established and recent
techniques such as the spectral relaxation and spectral quasi-linearization methods. Numerical
solutions for the heat transfer, mass transfer and skin friction coefficients have been presented
for different system parameters, such as heat generation, Soret and Dufour effects, chemical
reaction, thermal radiation influence, the local Grashof number, Prandtl number, Eckert number,
Hartmann number and the Schmidt number. The dependency of the skin friction, heat
and mass transfer coefficients on these parameters has been quantified and discussed. The
accuracy, and validity of the spectral relaxation and spectral quasi-linearization methods has
been established.
