Abstract
The curves of mass flow rates and temperatures as a function of time have a different shape from those for pressure in an orifice pulse tibe refrigerator. The relationship among them is analyzed to explain the distortion of mass flow rate and temperature oscillation curves measured in the past. The mass flow rate and temperature oscillations have fundamental oscillations and harmonics, where the frequency of the fundamental oscillation is the same as that of the suncusoidal 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.Citation
