A model is presented to describe radial heat transfer in a honeycomb monolithic structure under non-adiabatic, non-reacting conditions. This is believed to be the first model where the walls of the channels in the radial and tangential directions are considered to have a finite thickness. The model

β¦ Synopsis
Heat transfer in metal honeycomb monoliths, under non-adiabatic conditions, is considered in this work. Using a simple geometric simulation of the monolithic structure, steady-state heat balances are written separately for the solid and gas phases of the simulated monolith In the absence of chemical reaction the model is solved analytically to give solid and gas temperature profiles radially and axially within the monolith. An experimental system is used to compare heat transfer in a honeycomb metal monolith to the model predictions. Also, heat transfer in a packed bed of ceramic pellets is studied experimentally and compared to the metal monolith under similar, non-adiabatic conditions. Results point out the different heattransfer merits of each of these two bed configurations.
