Finite element modeling of a double-diffusive mixed convection flow of a chemically-reacting magneto-micropolar fluid with convective boundary condition

Abstract

In this paper, the steady, two-dimensional, heat and mass transfer flow of a chemically reacting mixed convection magneto-micropolar fluid over a wedge with a convective surface boundary condition is investigated. Using similarity transformations found by Falkner and Skan, the governing transport equations are reduced to a system of non-linear ordinary differential equations which are solved by employing the extensively-validated, finite element method. The results are depicted graphically to illustrate the influence of the various pertinent parameters on velocity, micro-rotation, temperature and concentration functions. Additionally, skin friction coefficient, local Nusselt number and local Sherwood number are also computed and presented graphically for the flow regime. The numerical solutions are compared with earlier studies for special cases of the wedge angle parameter and found to be in excellent agreement, thereby validating the accuracy of the present numerical code. The study finds applications in chemical reaction engineering processes, magnetic materials processing, solar collector energy systems, etc.
