摘要：A commercial computational fluid dynamics (CFD) package is used for numerical analysis of the oscillating fluid flow in a pulse tube cryocooler. This model uses helium as a working medium to achieve temperatures in cryogenic range by employing two pulse tubes with 180 . phase difference in the mass flow rate and the pressure at the cold end heat exchanger. The cryocooler comprises of compressor, after cooler, regenerator, pulse tube with cold and hot heat exchanger and the inertance tube. A two -dimensional axis symmetric model was used for simulation. This simulation demonstrates the variation in temperature and pressure with respect to time at the cold heat exchanger.
