This work presents an experimental analysis of free and forced convection due to a heated cylinder in a fluid-saturated porous medium. The resulting features of the temperature distribution under the action of a continuous and uniform air stream were investigated through the use of four different configurations: first, by inducing an air stream from below the heated cylinder; second, by placing an air stream on the left-hand side of the heat source; third by an air stream acting from the top of the heat source, and fourth by varying the injection angle. The consequences on the free and forced convection when all phenomena reach the steady state were analyzed by using an infrared camera. Close agreement is found through the conformed plumes with the theoretical solutions proposed by Kurdyumov and Liñán (2001).
