Study on Performance Improvement of a Double-acting Stiring Engine (Performance Evaluation of a New-type Matrix Geometric Pattern)

Abstract

In this study, the performance and characteristics of several types of a new matrix for a Stirling engine regenerator, called the "mesh sheet," were examined. The mesh sheets were installed in the SERENUM05 3-kW double-acting Stirling engine, and the performance of each matrix was examined from the perspective of engine operation. The specifications of the SERENUM05 engine and its measurement system are described in this paper. Based on the results of our experiments, the characteristic differences between the regenerators of the two-piston and double-acting engines were revealed. As a result, we clarified that the M3 mesh sheet produces the highest indicated efficiency among all the mesh sheets.
