Analysis of Homogeneous/Heterogeneous Reactions in an Electrohydrodynamic Environment Utilizing the Second Law

In this study, we investigate what happens to entropy in the presence of electrokinetic phenomena. It is speculated that the microchannel has an asymmetrical and slanted configuration. The presence of fluid friction, mixed convection, Joule heating, presence and absence of homogeneity, and a magnetic field are modelled mathematically. It is also emphasized that the diffusion factors of the autocatalyst and the reactants are equal. The governing flow equations are linearized using the Debye-Huckel and lubrication assumptions. The resulting nonlinear couple differential equations are solved using the program's integrated numerical solver, Mathematica. We take a graphical look at the results of homogeneous and heterogeneous reactions and talk about what we see. It has been demonstrated that homogeneous and heterogeneous reaction parameters affect concentration distribution f in different ways. The Eyring-Powell fluid parameters B1 and B2 display an opposite relation with the velocity, temperature, entropy generation number, and Bejan number. The mass Grashof number, the Joule heating parameter, and the viscous dissipation parameter all contribute to the overall increase in fluid temperature and entropy.

Automated summary

In this study, the effects of electrokinetic phenomena on entropy are investigated. The microchannel is modeled with an asymmetrical and slanted configuration, taking into account fluid friction, mixed convection, Joule heating, presence and absence of homogeneity, and a magnetic field. The governing flow equations are linearized using the Debye-Huckel and lubrication assumptions, and the resulting nonlinear couple differential equations are solved using Mathematica. Homogeneous and heterogeneous reaction parameters have different effects on concentration distribution, and the Eyring-Powell fluid parameters show opposite relations with various variables. The overall increase in fluid temperature and entropy is influenced by the mass Grashof number, Joule heating parameter, and viscous dissipation parameter.
