Entropy optimized MHD peristaltic movement of Johnson Segalman liquid with homogeneous heterogeneous reaction

This study examines a Johnson Segalman peristaltic movement over compliant curved channel walls that is electrically conductive and incompressible. Mass transfer analysis is carried out by the chemical reaction between two distinct species while taking homogeneous-heterogeneous phenomena into account. The flow modeling incorporates slip effects, heat generation/absorption, viscous dissipation, and Joule heating. The laws of conservation are used to model flows. By using lubrication theory assumptions and dimensionless variables, the mathematical equations of flow are made simpler. Here, the modeling equation for entropy generation is used to analyze irreversibility caused by heat, fluid flow, and Bejan number. The built-in ND Solve tool in Mathematica software is used to numerically manage the simplified system of equations. This command combines two numerical systems, RK-Fehlberg and shooting. The result and discussion section provides a full explanation of the physical behavior of flow quantities against the relevant parameters. It is observed that the Hartman number behaves in the opposite way on temperature and velocity profiles. Additionally, an enhancement in fluid concentration is noted for larger heterogeneous reaction parameter.
