Influence of compression-expansion effect on oscillating-flow heat transfer in a finned heat exchanger
Compression and expansion of a working gas due to the pressure oscillation of an oscillating flow can lead to a temperature variation of the working gas, which will affect the heat transfer in the oscillating ...

Acoustic impedance characteristics of linear compressors
The acoustic field of a linear compressor serves to deliver the compression work to the load, such as the connected cold head of a cryocooler; it plays an equivalently important role as the electrical and mech...

Performance of a precooled 4 K Stirling type high frequency pulse tube cryocooler with Gd2O2S
The efficiency of 4 K Stirling type pulse tube cryocoolers (SPTCs) is rather low due to significant regenerator losses associated with the unique properties of helium around 4 K and the high operating frequenc...

Temperature inhomogeneity in high capacity pulse tube cryocoolers
High power pulse tube cryocoolers are expected to be a very promising candidate for high temperature superconductors (HTS) cooling. Unfortunately there are still some problems significantly deteriorating the p...
