A09 Heat transfer characteristics and pressure drop of regenerator matrix using sintered metal fiber

Abstract

We focus on the high-porosity characteristics of sintered metal fiber matrix for Stirling engine regenerator. In order to measure its basic characteristics as regenerator, we measured heat transfer characteristics and pressure drop in comparison with stacked wire-mesh matrix. From the measurement results, sintered metal fiber matrix shows lower flow resistance and either equaling or surpassing heat transfer performance than stacked wire-mesh matrix.
