Thermodynamic cycles are very important and useful for understanding the mechanism of the pulse tube refrigerator. In this paper, two-dimensional axi-symmetric simulations of an inertance tube pulse tube refrigerator are conducted, and thermodynamic cycles of the gas parcels oscillating in regenerator are studied and analyzed in the Lagrangian's regime. The results show that the lowest temperature of the system is possibly decided by the amount of heat pumping by thermal cycles under different frequencies and charge pressure cases.
