✦ Synopsis

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 is solved numerically and is tested on recently published experimental data. The rigorous analysis of temperature profiles in the monolith structure facilitates future extension of the model to include homoeeneous and heterogeneous reaction terms. Initial conditions at the inlet and outer walls of the monolith m"y readily be varied in the model. It is shown that if these are oversimplified then this will lead to inaccuracies in the prediction of temperature profiles within the monolith.

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
