Optimising the flow within a Stirling pulse tube cryocooler

, 2018
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
