โœฆ Synopsis

The relationship among the curves of mass flow rate, temperature and pressure as a function of time in an orifice pulse-tube refrigerator is analyzed to explain the previously measured distortion of mass flow rate and temperature oscillation curves. The mass flow rate and temperature oscillations are described in terms of fundamental oscillations and harmonics, where the frequency of the fundamental oscillation is the same as that of the sinusoidal pressure oscillation. The time-averaged enthalpy flow rate and other energy flow rates are expressed in terms of the amplitude and phase of the fundamental oscillation of the mass flow rate through the orifice.

This paper analyzes direct current flow (DC flow) due to double-inlet, and introduces a second orifice version pulse tube refrigerator experiment to diminish DC flow. Analysis based on some assumptions shows that DC flow through the double-inlet valve in the pulse tube refrigerator is not generally
