Comparative Thermo‐Solutal Transport and Entropy Analysis of Casson–Maxwell Fluid Flow Over a Darcy–Forchheimer Porous Region With Slip Effects

ABSTRACT

The present study focuses on irreversibility distribution analysis and minimization of entropy production in the unsteady circulation of highly ordered chemically reactive binary non‐Newtonian fluid induced by a non‐uniformly moving stretchable membrane. The membrane is in a Darcy–Forchheimer porous region driven by nonlinearized thermal radiation and a time‐dependent magnetic field. Appropriate nondimensional transformations are employed to simplify the governing equations of fluid motion into ordinary differential form. The MATLAB (bvp4c) generated plots illustrate the distribution of entropy generation and irreversibility for varying governing parameters, accompanied by corresponding physical analysis. Additionally, the tabulated data highlight the numerical influence of material parameters on skin friction, heat and mass transfer rates alongside comparative analyses tables referencing previous studies. The present article concludes that entropy generation can be effectively minimized by making use of Casson fluid over Maxwell fluid and controlling the porous conditions of the system so as to improve the efficiency of industrial machineries. However, for higher values of inertial and non‐inertial porosity parameters, the entropy production drops by 40% to 50% from Maxwell fluid to Casson fluid on the surface, which signifies the enhanced performance of Casson fluid in efficient industrial devices.
