Abstract

Flow leakages in fixed-matrix regenerators consist of pressure leakage through valves and through the cracks (in regenerator housing for very high temperature heat recovery applications) and carryover leakage to and from the ambient to the matrices. These leakages have a detrimental effect on the regenerator heat transfer performance, and hence such effects should be properly taken into consideration for design and analysis of regenerators. In this regard, for the first time a detailed leakage flow network modeling is developed and is combined with heat transfer and pressure drop modeling for the design and analysis of fixed-matrix regenerators. Considering a single component model for the gases, the model developed in the paper has 52 unknowns, and 52 equations are outlined in the paper for the solution.
