Numerical analysis of stirling engine

Research output: Contribution to journalArticle

Abstract

A simulation model developed for research and development of the Stirling engine known as NS 30 S is discussed in this paper. This model is based on the 3rd-order method, for which fundamental equations are derived from the conservative equations of mass, momentum and energy, and numerical model of the system for balancing pressures in four cylinders is included to correspond with the double-acting type Stirling engine NS 30 S. The calculated results are inspected in comparison with the experimental results. Also, by means of the developed simulation model, a comparative study of the engine performance in the case employing helium and hydrogen as the working gas is conducted from the viewpoint of thermophysical properties, and, by clarifying the characteristics of heat transfer and gas flow, the effects of the temperature conditions for driving are investigated. In addition, the particulars of the heat exchangers are evaluated as to design optimization.
