This paper analyzes the mechanism of the symmetry-nozzle instead of needle valve or oriยฎce to improve the performance of pulse tube refrigerator in experiments. Their identiยฎcations are to result in a similar reciprocal movement in the hot end of the pulse tube; their dierences are that their ยฏow co
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 valid
A two-stage pulse tube refrigerator in combination with a rotary valve and a valved compressor has been constructed. Its performance and the effects of the operating parameters were investigated. A minimum temperature of 11.5 K and a cooling capacity of 1.3 W at 20 K were obtained at a frequency of
