Abstrakt

The role of pulse tube in PTR system is twofold, namely the thermodynamic and the dynamic aspects. The thermodynamic aspect determines the refrigeration mechanism of pulse tube, which in turn exerts dynamic influence on PTR system. The method proposed by Dr. de Boer has been developed to investigate the displacement of gas in pulse tube of a PTR system. The computational result and the discussion on it are presented here.
