Numerical Analysis of Stirling Engine (3rd Report, Investigation of Engine Particulars)

For the purpose of predicting and evaluating of the Stirling engine performance in detail, the cycle simulation code requires a technique for the 3rd-order method. The first paper presented our code which was useful in the research and development of our Stirling engine NS 30 S. In the second paper, a comparative study of working gases (helium and hydrogen) was carried out, and the effect of the test conditions of temperature was investigated. In addition, the calculated results were inspected in comparsion with the experimental ones This paper describes the test conditions of pressure and the cylinder volume and the piston phase angle affecting the Stirling engine performance and design. Then, the particulars of heat exchangers are evaluated as to design optimization. As a result, it is verified that our code is an available tool for optimizing the Stirling engine design.
