Cross diffusion, radiation and chemical reaction effects on MHD combined convective flow towards a stagnation-point upon vertical plate with heat generation

The impacts of cross diffusion on stagnation point MHD combined convective flow approaching a plate which is upright in a porous surrounding subject to chemical reaction, heat generation and radiation is explored. Relations of similarity are employed for the conversion of flow relations as ordinary differential equations upon the application of relations of similarity, shooting method and Runge-Kutta algorithm are applied to find the solution. An analysis is made upon the graphical depictions on velocity of the liquid, its temperature and its concentration with respect to some physical entities and conclusions drawn. It is noticed that velocity shoots up across the boundary layer with a rise in heat generation, Dufour number and Biot number whereas it reduces for strong chemical reaction. For ascending values of Dufour number, chemical reaction parameter and Biot number, the temperature soars up and as a result, thickness of thermal boundary layer inflates.
