The resulting differential equations were treated by numerical methods using the alternating directions implicit method (ADI), which is one of the finite differences methods, and in both cases: unsteady state and steady state. And we completed the study of the effect for each of: Prandtl number, Schmidt number, Gratshof number, and Radiation parameter. %K Heat Transfer %K Porous Medium %K Prandtl Number %K Schmidt Number %K Gratshof Number %U http://www.oalib.com/paper/5431093
