Radial thermal conductivities in packed beds have been extensively studied and correlated, but there is little published work on axial conductivities. The data on axial conductivities that is available is limited to low flow rates because of measurement difficulties at high flow rates. In this paper, a method is presented for estimating the values of axial thermal conductivities at high flow rates from the existing data on radial thermal conductivities. The necessity for considering packed bed axial conduction in design work can be determined from these results.
