Abstract

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.
