Abstract:The research in this article is carried out to study incompressible and unsteady free convective flow on a semi- infinite isothermal vertical plate in a doubly stratified non-Darcian porous media with variable mass diffusivity and variable thermal conductivity. The governing non-linear partial differential equations of flow were calculated by applying an implicit finite difference scheme of the Crank-Nicolson type. ; Various parametric impacts on concentration profiles, temperature, velocity, as well as Sherwood number, Nusselt number, and skin friction, were examined and presented in graphs. It is examined that there exists a significant temperature decrease for high Darcy number in stratified fluids. Also, it is detected that the presence of stratification produces a considerable drop in skin friction while increasing the mass and heat transfer rate. Results from the present were compared to available solutions, and they matched up well.
