A FEM and FDM integrated approach for analysis of performance and characteristics of a converter
A three-dimensional numerical model for a metal monolithic converter was developed to simulate its performance and analyze its characteristics. The employed numerical scheme incorporates the finite element method for analyzing heat conduction in solids of monolith substrate and the finite difference method for simulating physical and chemical phenomena in each of the monolith channels. Satisfactory solution is obtained by a convergent iteration between the FEM and the FDM modules at each time step. The fact that the simulation and measurement agree well verifies the validity of the three-dimensional model and the numerical approach used in this study.
