Description
Summary: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 heat-transfer merits of each of these two bed configurations.
