Entropy generation analysis in unsteady flow of micropolar fluid through anisotropic porous media

In this study, the authors have addressed the time-dependent flow of micropolar fluid in a channel filled with an anisotropic porous medium. The novelty of the present investigation lies in using a complex porous medium along with the slip conditions on both geometry boundaries and analysis of entropy generation in the micropolar fluid flow through anisotropic porous media. The non-linearity of the governing equations has been solved by the finite difference method, and the solution obtained is stable and convergent. The numerical solution of the dependent variable has been utilized to determine the variation in the flow profile due to the porous medium’s complex nature, to see the effect of slip boundary conditions, and the effect of non-Newtonian fluid parameters. The variation in the velocity profile and temperature profile with respect to the flow parameters is satisfied with the physics of the flow and the medium. An important conclusion made is that the entropy generation in the flow of micropolar fluid through anisotropic porous media can be reduced by raising the anisotropic angle and anisotropic permeability parameter, which can be utilized for the modeling of heat exchangers, microfluidic devices, thermal management in porous microchannels, porous solar collectors, and many more.
