Yuan Research and Development Division Lockheed Martin Missiles and Space Co. Palo Alto, CA 94304, U.S.A. ABSTRACT A third order computer model has been developed by modifying the Stirling Refrigerator Performance Model (SRPM), which has been validated extensively by various Stirling Refrigerators in the literature. The resulting computer program known as the Pulse Tube Refrigerator Model (PTRM) has been validated by two different pulse tube coolers. The result on the validation of a large laboratory pulse tube refrigerator built by the National Institute of Standards and Technology will be reported elsewhere. In this paper, the predicted performance of a pulse tube cooler developed by Lockheed in 1987-88 is compared with the experimental data. Good agreement was found between the two.
