Abstract

The size of heat exchanger flow passages may limit performance when the characteristic length of the passage (e.g. Darcy characteristic length Lc) is reduced. We have conducted heat transfer experiments with stainless steel screen regenerator stacks (500 mesh). The data obtained with nitrogen near 1 atm show limitations on the heat transfer at flow rates corresponding to Reynolds numbers Re<<1; (Re based on Lc). The order of magnitude of the thermal conductances has been found to be 10-4 W/(cm2K) in the flow rate range covered.
