SEPULVEDA, CAROLINA; AMELL, ANDRÉS  and  CADAVID, FRANCISCO. DEVELOPMENT OF A METHODOLOGY FOR DESIGNING AND CHARACTERIZING HONEYCOMB HEAT REGENERATORS. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.164, pp.200-208. ISSN 0012-7353.

In this study, a methodology for designing and characterizing honeycomb thermal regenerators is proposed, using the Computacional Fluid Dynamic CFD software FLUENT to obtain temperature profiles and correlations for relating numerical results with performance indicators such as effectiveness and heat recovery rate. Additionally, relevant thermal parameters such as convective coefficient of heat transfer and NTU are determined using empirical correlations. This methodology has a low computational cost and allows the selection of regenerators from commercially available geometries. The methodology was applied to the characterization of a 400 cells per square inch (CPSI) regenerator embebed in a self-regenerative burner. Results were compared with experimental data and a good approximation was obtained.

Keywords : Design methodology; ceramic thermal regenerator; honeycomb; CFD; FLUENT; effectiveness; heat recovery.
