This paper is mainly concerned with the investigation of steady, three-dimensional flow of H2O/NaC6H9O7 base fluids with Fe3O4/Al2O3 nanoparticles past a Riga plate implanted in a non-Darcian porous medium with internal heat generation/absorption effects. Water (H2O) and Sodium Alginate (NaC6H9O7) are the base fluids, whereas Magnetite (Fe3O4) and Aluminium oxide (Al2O3) happens to be the nanoparticles. The numerical plan for non-Newtonian fluid Sodium Alginate is isolated through the Casson model. Suitable transformations on governing equations yield strong non-linear differential equations. The non-linearity of the basic equations and additional mathematical difficulties led to use numerical method. Plots for the outcomes of various related variables are furnished. The local skin friction coefficient and the local Nusselt number have been expounded. The results end up to signify that the local skin friction coefficient and the local Nusselt number are diminished for larger values of porosity parameter and the local inertia coefficient.
