Embedded in a Porous Medium

Abstract
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
).
