A13 .Performance of a Stirling engine with dead volume positively added between the high temperature heat exchanger and the expansion piston
Details
This paper deals with an engine added a relatively large dead volume between the high temperature heat exchanger and the expansion cylinder, after a pulse tube refrigerator. This would improve seal performance at the expansion cylinder. P-V diagram derived from the measurement is almost the same as that obtained from multi-element simulation. The phase angle and the amount of regenerator matrix of the engine are near the optimum. The length of pulse tube can be shortened to improve output with little effect of efficiency.
