Summary: We study numerically a two-dimensional steady convective flow of micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux. Using Darcy-Forchheimer model, the corresponding momentum, microrotation and energy equations have been solved numerically. The local similarity solutions for the flow, microrotation and heat transfer characteristics are illustrated graphically for various material parameters. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and heat transfer are also calculated. It is shown that large Darcy parameter leads to decrease in velocity while it increases the angular velocity and temperature of the micropolar fluid. The rate of heat transfer in weakly concentrated micropolar fluids is higher than in strongly conectrated micropolar fluids.
