In the above paper the authors treat the natural convection boundary layerflow in a Darcy-Brinkman-Forchheimer porous medium. In the energy equation theradiation effect has been taken into account. A two-parameter perturbationmethod is used for the solution of the equations. The first order results arepresented in tables and figures. This is an interesting work but there are someweak points which are presented below:
