Abstract
This work analyzes the impact of oriented magnetic fields and thermal radiation on the entropy generation of two non-miscible electrically conducting micropolar and Newtonian fluids in a horizontal rectangular porous channel. In this model, the walls of the duct are considered perfectly isothermal and the flow inside the porous channel takes place in the presence of an inclined magnetic field. Expressions for heat transformation, fluid flow velocity, Bejan number distribution, and entropy production characteristics are obtained with the help of a reliable method. To achieve the objective of the problem, the authors used the continuity of temperature distribution, thermal flux, shear stress, linear and angular velocity over the fluid–fluid interface and no-slip conditions at the fixed plates of the duct. The impact of various emerging parameters on the entropy optimization, Bejan number, heat transformation, and flow velocity is analyzed. Our findings are validated by the previously established results.
