Abstract
This problem deals with the effects of double diffusive, mixed convective flow of an incompressible viscous fluid through a vertical heated plate
embedded in a non-Darcy porous medium under the influence of variable fluid properties numerically. The governing equations are modeled for the
double diffusive boundary layer flow to understand the behaviour of velocity, temperature and concentration for variable fluid properties namely
permeability, porosity, thermal conductivity and solutal diffusivity of the physical modal. Using a suitable similarity transformation, the highly nonlinear coupled PDE's are reduced into a set of coupled ordinary differential equations. By applying the Shooting technique with the help of RungeKutta-Fehlberg integral scheme and Newton-Raphson method, numerical computations have been carried out and are illustrated through the graphs
to analyze the behaviour of velocity, temperature, concentration, Skin friction, Nusselt number and Sherwood numbers for the non-dimensional
parameters of the physical system for both uniform permeability and variable permeability. To validate our numerical scheme, present results are
compared with previously published work in the absence of few non-dimensional parameters and found to be in good agreement up to six decimal
places of accuracy.
