Study of Regenerator Using for a 3kW Stirling Engine

Abstract

The regenerator losses of a 3-kW Stirling engine are analyzed in detail. By adopting a unique cylinder arrangement and a well-designed heat exchanger system for the engine, a fifty-percent indicated efficiency and a lower regenerator loss were obtained. To clarify the regenerator performance, the regenerator losses of the engine are rearranged by using reliable experimental data and analyzed data by a mathematical model. Also, the regenerator losses are analyzed with a proposed method, which is able to derive reasonable regenerator losses from engine operating data.
