Mixed convective MHD flow of a micropolar fluid with ohmic heating, radiation and viscous dissipation over a chemically reacting porous plate subjected to a constant heat flux and concentration gradient

Abstract

In the present paper analysis of a chemically reacting mixed convection MHD micropolar flow, heat and mass transfer in porous medium with the effects of ohmic heating, radiation and viscous dissipation past an infinite vertical plate which is subjected to a constant heat flux and the concentration gradient. The non-linear coupled partial differential equations are solved numerically using an implicit finite difference scheme known as Keller-box method. The results for concentration, transverse velocity, angular velocity and temperature are obtained and illustrated graphically to observe the effects of various parameters, and the numerical discussion is presented with physical interpretations.
