Heat transfer from a circular cylinder with constant heat flux placed in a saturated porous medium and subjected to cross flows is studied both analytically and experimentally. Order of magnitude analysis reveals two distinct regimes present during the transient process; the heat transfer for small times is dominated by conduction, but it is eventually balanced by convection at a large time. It is also derived analytically that for a given heat flux the mean surface temperature rise at steady state depends on the cross-flow velocities. At steady state the wall temperature is not uniform, but varies along the circular position. Experimental work is conducted in order to verify the analytical results. It appears that the analytical predictions reasonably agree with the experimental results.
