AB - This study deals with the investigation of the effects exerted by heat radiation and a first-order chemical reaction on the magnetohydrodynamics boundary layer slip flow which is established past a vertical permeable surface embedded in a porous medium (with uniform heat and mass flux). The heat equation includes the relevant terms, i.e. the viscous dissipation, radiative heat flux, Ohmic dissipation, and absorption of radiation. The mass transfer equation takes into account the effects related to the chemically reactive species. A classical model for optically thin media is used for studying the effect of radiation. The resulting non-linear coupled partial differential equations are solved by a perturbation technique. The results show that the velocity, temperature and concentration fields are appreciably influenced by the presence of chemical reactions, thermal stratification and the imposed magnetic field. The effects of various parameters on the skin-friction coefficient are also assessed.
