Abstract: In the current research work we scrutinised the radiation and cross diffusion influences on unsteady stream through an elongated plate in the heat generating porous matrix with chemically sensitive process. The modelled PDEs are transfigured into ODEs with the utility of similarity transformation. Runge-Kutta integration procedure together with shooting technique is adapted in this work. The dominations of various parameters are demonstrated with the help of graphical representations. Further numerical discussions for skin drag coefficient, Nusselt number and solute dispersion are investigated. The solute and heat transfer rates accelerates by increasing suction/injection parameter with decreasing Hartmann number. The magnitude of skin friction and localised Nusselt number declines when enhancing Dufour and Soret values.
