The Analysis of Performance of Stirling Engines : 1st Report, Computer Simulation Model

Abstract

The operating data of Stirling engines are necessary in the process of developing or designing them, but they are not available enough. This paper describes the development of an accurate computer simulation model for predicting the performance of Stirling engines to complement those operating data. Though the model represents the working space by 43 successive control volumes, the method employed here can save its computing time. The model also takes into consideration the leakage of working gas through the piston ring which may affect the performance of Stirling engine to a large extent. The model was applied to a large marine Stirling engine and the calculated results show good agreement with the experimental ones.
