The paper presents the numerical investigation of the convection heat and
mass transfer in a hydromagnetic Carreau fluid past a vertical porous plate
in presence of thermal radiation and thermal diffusion. The non-linear
partial differential equations governing the flow are transformed into
ordinary differential equations using the usual similarity method and the
resulting similarity equations are solved numerically using Runge-Kutta
shooting method. The results are presented as velocity, temperature and
concentration profiles for different values of parameters entering into the
problem. The effects of suction, magnetic field, thermal radiation and
thermal diffusion on the skin friction, rate of heat transfer and mass
transfer are presented numerically in tabular form.
