Studying Effect of Activation Energy and Chemical Reaction with Heat and Mass Transfer of Maxwell Fluid on Riga Plate Embedded in Porous Media

Abstract

This present article delves the behavior of a Maxwell fluid flow over a Riga plate nestled in a porous media, examining chemical reactions, activation energy, coupled with heat and mass transfer simultaneously. The governing system of highly coupled, nonlinear PDEs is transformed into a set of ODEs through suitable application of similarity transformations. Accuracy in the solving of the resulting system of ODEs was achieved through the application of the Bvp4c solver in MATLAB. A thorough parametric study has been performed to check the influences of different physical quantities such as Deborah number, porosity number, modified Hartmann number, thermal and mass Grashof numbers, velocity slip parameter, Stefan-Boltzmann coefficient, Prandtl number, radiation parameter, thermophoresis & Brownian motion parameter, Eckert number, Schmidt number, chemical reaction parameter, temperature difference parameter, and activation energy, suction/injection coefficient, and concentration slip parameter. The velocity, temperature, and concentration profiles effected by these parameters are extensively analyzed graphically and through tabulated data. The results serve as a basis for understanding the control mechanisms for non-Newtonian fluid flows in engineering and industrial processes involving porous media and electromagnetic fields.
