In designing Stirling engines stacked wire gauzes are often used as the regenerator matrix, but the choice procedure is not specified yet. In the previous paper, the fundamental characteristics of wire gauzes on the flow friction and heat transfer were studied by steady flow experiments and a theoretical analysis was made on the thermal behavior of the matrix. Based on these results, a method to choose stacked wire gauzes for a regenerator matrix was presented. The aim of this paper if to confirm the validity of the choice procedure. First, the optimum matrix for an experimental engine is chosen. Second, the matrices of various gauze materials and mesh numbers are set up at a constant heat capacity. Finally, engine data are compared with theoretical predictions of each matrix performance.
