The governing non-linear partial differential equations of flow were calculated by applying an implicit finite difference scheme of the Crank-Nicolson type.}, abstract={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.}, type={artykuł}, title={Variable thermal conductivity and mass diffusivity effects in a free convective flow of doubly stratified non-darcian porous medium over a vertical plate}, keywords={mass diffusivity, non-Darcy, porous medium, stratification, thermal conductivity}, }
