Effect of chemical reaction and activation energy on Riga plate embedded in a permeable medium over a Maxwell fluid flow

Abstract

This study delves into the intriguing interplay between activation energy, chemical reactions, no-slip effects, and radiation on the flow dynamics of a Maxwell fluid over a Riga plate nestled in a permeable medium. By initially formulating partial differential equations, which are then transformed into a set of ordinary differential equations using adept similarity transformations, we embark on a numerical journey aided by MATLAB. Unraveling the intricate tapestry of influences, we meticulously scrutinize the impact of activation energy, chemical reaction rates, no-slip parameters, and radiation on various flow characteristics. We explore the ramifications of velocity, energy distribution, skin friction, concentration profiles, and Nusselt number distributions through insightful plots. The essence of our findings reverberates throughout engineering and industrial domains, potentially reshaping practices and procedures. Our key revelations echo a narrative where heightened activation energy and adherence to no-slip conditions accentuate concentration profiles, contrasting the decrement induced by chemical reactions.
