Abstract

In the first paper, we presented the cycle simulation code of the Stirling engine, which was useful for researching and developing NS 30 S by virtue of predictions and evaluations. It was found that the calculated values of the engine performance and the P-V diagram were in good agreement with the experimental ones. In this paper, a comparative study of the engine performance in the case of using helium and hydrogen as the working gas is made from the viewpoint of thermophysical properties. By clarifying the characteristics of heat transfer and flow rate, the effects of heater tube temperature and cooling water temperature are investigated. In addition, the calculated results are inspected in comparison with the experimental ones concerning the test condition of temperature.
