**Abstract**

We study, the effect of thermal radiation and viscous dissipation on steady MHD free convection and mass transfer flow of a micropolar fluid with constant heat and mass fluxes. The diffusion thermo, thermal diffusion, viscous dissipation and Joule heating have been considered for high speed fluid. The governing equations of the problem contain the partial differential equations which are transformed by similarity technique into dimensionless ordinary coupled non-linear differential equations. The dimensionless governing equations are solved numerically by using fourth order Runge–Kutta shooting iteration technique. We investigate in detail the distributions of velocity, microrotation, temperature and concentration across the boundary layer and also evaluated the skin friction, couple stress, the rate of heat and mass transfer at the plate.
