N. Kagawa, ANALYTICAL METHOD FOR STIRLING ENGINES AND COOLERS, JSME international journal. Series B, fluids and thermal engineering, 41(3), 1998, pp. 632-640
For aiding the design and improving the performance of various Stirlin
g engines and coolers, a Stirling engine thermodynamic and mechanical
analysis, SETMA, has been developed and examined. A simple SETMA, whos
e working space is divided into five control volumes, has been develop
ed to enable easy, accurate prediction of the performance of Stirling
machines. In this paper, the SETMA and fundamental equations are given
in detail. Several examinations of the applicability of SETMA are dis
cussed, comparing the calculated and experimental results of two types
of actual engines. The calculation accuracy can be markedly improved
by optimizing the friction-loss factors and heat transfer coefficients
and carefully scanning of the dimensions of the working space. For ca
lculations of the thermodynamic properties used by SETMA, it was clari
fied that the SRK equation of state is more reliable than the ideal-ga
s equation when analyzing higher-pressure-charged Stirling machines.
