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 polyno

In a general GM type orifice pulse tube refrigerator, there are two short periods during which both the high pressure valve and the low pressure valve are closed in one cycle. We call the short period 'waiting time'. The pressure differences across the high pressure valve and the low pressure valve
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
