Analysis of Arrhenius activation energy in an electrically conducting fluid flow with chemical reaction and viscous dissipation

Abstract

This study takes into account the effects of Arrhenius activation energy on the fluid, the viscous dissipation of the fluid, and the chemical reactions in the fluid as it investigates recent advancements in electrically conducting reactive fluid flow on an extended porous surface. By applying a uniform magnetic field that is orthogonal to the fluid flow, the related nonlinear partial differential equations are generated and analysed. After including similarity variables into the flow, the resulting equations are transformed to dimensionless form and numerically solved using the finite difference method. Upon solving the equations using computer-generated methods, graphs and tables will be presented for analyzing the elements influencing the flow. This study attempts to illustrate that the Arrhenius energy activation parameter influences the concentration profiles by enhancing them, despite the fact that the rate of the fitted fluid displays contradictory characteristics. In addition, the impact of the Schmidt number, the Nusselt number, and the Sorret parameter on the flow will be investigated, and the velocity and temperature profiles will be graphically shown.
