Parametric Numerical Study of Off-Axis Pulse Tube Losses
Recently there has been an emphasis on applying numerical modeling, with varying degrees of complexity, to the study of the notorious sensitivity of the pulse tube cryocooler to off-axis operation. Previous work has demonstrated the suitability of applying multi-dimensional CFD simulation to the pulse tube cryocooler both as a whole and at the component level for qualitative and quantitative an...
متن کاملDevelopment of the Pulse Tube Refrigerator as an Efficient and Reliable Cryocooler
This paper presents a review of the pulse tube refrigerator from its inception in the mid-1960s up to the present. Various factors are discussed which brought it from a laboratory curiosity to the point where it is now the most efficient of all cryocoolers and reliable enough to be used on space missions. Carnot efficiencies as high as about 20% at 80 K and temperatures as low as 2 K have been ...
متن کاملCFD analysis of a single stage pulse tube cryocooler with two double inlet valves
The internal working processes in pulse tube cryocooler (PTC) are quite complex due to the unsteady, oscillating compressible gas flow in the pulse tube. Although considerable theoretical studies have been carried out as of date phenomena occurring in a pulse tube cryocooler are still to be understood. The present research work is carried out in order to understand the cooling mechanism and to ...
متن کاملInertance Tube Modeling and the Effects of Temperature
Pulse tube refrigerators (PTRs) have made dramatic improvements in reliability, efficiency and usage. Inertance tube PTRs have been one of the keys to these improvements. The inertance tube is the component in the PTR that most easily affects the control of the PTR fluid dynamics. In one application in multistage cryocoolers, the performance of inertance tubes at the cryogenic temperatures is o...
