Abstract

A three-dimensional numerical model is established which is for studying the unsteady thermal process in honeycomb regenerator. The numerical simulation was performed using FLUENT, a commercial Computational Fluid Dynamics (CFD) code, to compare simulation results to the test data. The temperature distribution of flue gas and air along the length way were obtained. The influence of switching time on the heat exchange is investigated as well. And the factors that influencing the best switching time were studied. The work in this study provides a theory basis and guide to the exploitation and appliance of HTAC system and the results of the numerical calculation can be used as the foundation of engineering design. The results may be utilized for design of porous media reactors and process optimization.
