Investigation of Regenerator Characteristics for Miniature Stirling Cryocooler in LN2 Temperature Range |
| |
Abstract: | It is very important for optimizing the design parameters and gaining high performance to determine the entropy loss rate of the regenerator in a Stirling cryocooler, this topic is having been in hot debate. In this paper, a theoretical model and its controlling equations are set. By being processed in dimensionless method and simplified rationally, a leading order controlling equation and an entropy flux equation are derived. |
