Among numerous methods which have been employed to reinforce the thermal efficiency in many systems, one is the thermal radiation which is a mode of heat transfer. Another way to improve the thermal efficiency is the utilization of the porous media. The present work includes the study of micropolar flow with allowance for thermal radiation through a resistive porous medium between channel walls. The governing coupled partial differential equations representing the flow model are transmuted into ordinary ones by using the suitable dimensionless coordinates, and then, quasi-linearization is employed to solve the set of relevant coupled ODEs. Effects of physical parameters on the flow under different conditions, arose by varying the governing parameters, are scrutinized and discussed through tables and graphs. A comparison is associated with previously accomplished results and examined to be in an exceptional agreement. The culminations evidently disclose that the porosity parameter and the Reynolds number suppress the microrotation and velocity, while material parameters produce opposite effects. The thermal radiation phenomenon downturns the temperature curves and enhances the heat transfer rate on the lower wall of channel.
