Abstract
The purpose of this study is to inspect the flow of magneto-hydrodynamic third-grade liquid through Darcy-Forchheimer's porous space with variable features. Energy expression is explored by the convective condition and Joule heating effect. Features of homogeneous-heterogeneous reactions are accounted. Both auto-catalysts and reactants are considered equal diffusion coefficients. The incompressible liquid is conducted electrically. Proper variables convert the nonlinear flow systems to ordinary ones. Then the HAM technique is implemented for the series solution. The upshots of various variables such as the Magnetic variable, diffusion coefficient ratio parameter, Baiot number, and Prandtl number are displayed graphically. Numerical data of drag force is executed and elaborated. Our outcomes declared that temperature gradient enhances with increment in magnetic parameter and Biot number. Moreover, concentration shows a contrary trend against higher strength of homogeneous and heterogeneous reactions.
