Abstract

This article deals with the electromagnetohydrodynamic Casson Nanofluid flow induced by a stretching Riga plate in a non-Darcian porous medium under the influence of internal energy change, Arrhenius activation energy, chemical reaction, and Melting heat transfer. The flow motion is induced as a result of the introduced mechanism that capable of controlling or assisting a weakly hydromagnetic fluid flow process called the Riga plate. In most of the literature, the thermophysical properties of the fluid are assumed to be constant. However, this present study bridges this gap by assuming that viscosity, conductivity, and diffusivity are all temperature-dependent. Also, the exponential decaying Grinberg term is used as a resistive force in this investigation due to the electromagnetic properties of the Riga plate in the momentum conservation equation. The resulting coupled nonlinear ordinary differential equations are solved by optimal homotopy analysis method (OHAM) and validated with Galerkin weighted residual method (GWRM). The results reveal that; Casson fluid exhibits a solid characteristic when yield stress is more than the shear stress, also the chemical reaction parameter reduces the nanoparticle volume fraction. Moreover, this article includes some future recommendations.
