Magnetohydrodynamic (MHD) Convective Flow through a Porous Medium with Magnetic and Chemical Reaction Characteristics

Abstract

In this analysis, MHD convective flow in a porous medium with magnetic and chemical reaction characteristics were examined. We modeled the governing Partial Differential Equations (PDEs) in dimensional form viz: continuity, momentum, energy and mass. Furthermore, using suitable dimensionless quantities they were transformed and Finite Difference Method (FDM) was employed to deduce approximations for the velocity, temperature and concentration. Numerical experiments were conducted to study and explain the influence of parameters of physical interest associated with the fluid flow. It is found that the concentration and velocity of the fluid rise with increase in negative values of chemical reaction and an opposite trend was seen when increased with positive values.  It is also exhibited that the momentum boundary layer becomes lower as the Hartman number becomes significant.
