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

โฆ Synopsis
An integration formula of enthalpy flow rate along a pulse tube in pulse tube refrigerators is described on the assumption of sinusoidal mass flow rate and sinusoidal pressure fluctuation. For ideal double inlet and ideal orifice pulse tube with helium as working medium, it is simplified to a polynomial formula. Polynomial formulas for roughly evaluating the volume of the pulse tube in ideal double inlet and ideal orifice pulse tube refrigerators are also given.

Existence of steady large-scale streaming within basic pulse tube refrigerators was shown analytically. The steady component of the second-order axial velocity and the axial streaming velocity were obtained from the first-order solutions of continuity, momentum and energy equations, assuming that th
