Abstract

One of the key requirements for successful operation of Stirling pulse tube cryocoolers is to minimise flow mixing within the pulse tube. This requires careful design of the inlet and outlet to the pulse tube. In this study, the ow within the pulse tube of an existing cryocooler is numerically analysed. Thereafter, alternative inlet/outlet designs are suggested and analysed in order to optimise the flow within the pulse tube cryocooler. The numerical simulation have been carried out using CONVERGE CFD, a finite volume Navier-Stokes solver. The standard k − ε RANS turbulence model has been used to account for the effects of turbulence within the pulse tube.
