THERMAL AND FLUID FLOW FIELDS IN A REGENERATOR WITH CERAMIC CHIMNEY BLOCK CHECKER WORK

Abstract

Selected results of mathematical modelling and computer simulation of transient conjugate heat transfer in a vertical contraflow glass furnace regenerator are reported. The problem is solved three-dimensionally (3D) using the ANSYS 8.0 /FLOTRAN program. The main regenerator fluid flow and thermal fields about a cyclic equilibrium of the regenerator are visualized. Heat and fluid flow parameters for the regenerator’s cyclic equilibrium are presented by Tm = Tm(H',t); Tm,f = Tm,f (H',t); hm = hm(H',t); V = V (H',t); k = k(H',t) and ε= ε(H',t) graphics. Remarks about transient heat transfer in this kind of regenerators are made based on the obtained numerical values and relationships.
