...George-Rafael Domenikos; Emmanouil Rogdakis; Irene Koronaki The aim of this work is to analyze a superfluid Stirling cryocooler using superfluid helium as the working medium. The idea behind this kind of cryocooler is to utilize two conjoined Stirling coolers with a phase difference as to achieve...

...Isares Dhuchakallaya; Patcharin Saechan This study examined the influence of an in-line phase-adjuster on the energy conversion efficiency of a thermoacoustic Stirling heat engine (TASHE). The numerical and experimental investigations were performed. An acoustic field in the system can be adjusted...
