✦ Synopsis

We study the forced convective heat transfer from a uniform temperature cylinder placed perpendicular to an otherwise uniform fluid stream in a porous medium at finite values of the Péclet number. Attention is focused on how the absence of local thermal equilibrium between the solid and fluid phases affects the temperature fields of the two phases and the rates of heat transfer from the cylinder. Detailed numerical results are given for a wide range of parameter values. On the upstream side of the cylinder the temperature field extends further from the cylinder in the solid phase than it does for the fluid phase, but the opposite is true on the downstream side.
