Entropy generation analysis on mixed convection dissipative flow of MHD chemically reactive micropolar fluid with thermo-diffusion effect

Abstract

The research presented in the study provides a fundamental understanding to minimize the irreversibility process in a micropolar flow system, which is essential in the field of Bio-engineering and  various designing. In the study of micropolar fluids, the vortex viscosity and scaling material parameters play a crucial  role and influences the dynamics of micropolar flow. The flow of a micropolar fluid through a permeable semi-infinite oblique plate submerged in a porous medium has been studied theoretically using an unstable combined convection process. The dynamical equations, which are first non-dimensionalized by using a set of dimensionless quantities, are solved by creating an asymptotic multi-parameter perturbation method. The thermodynamic analysis on entropy generation is also performed for variour flow parameters. It is noticed from the analysis that when the magnetic field parameter (M) changes from 1.0 to 2.0, the entropy generation upsurges by nearly 32 to 49 percent. It is also recorded that when Brinkman number (Br) increases from 0.5 to 1.5, the entropy generation number  increases drastically by 33 to 50 percent approximately.
