With the development of the frontier domains such as quantum computing, condensed matter physics and space exploration, there is an urgent need for the multi-stage ultra-low temperature refrigerators to reduce the internal thermal noise and external thermal interference. The superfluid 4He system is a key component at the 1 K stage of ultra-low temperature refrigerators. The cooling capacity...

Throughout the progression of particle accelerator technology, there has been a significant upsurge in the demand for cooling capabilities within the superfluid helium temperature range. The integration of cold compressors not only minimizes the size of heat exchangers but also optimizes the utilization of cold exergy. In the context of multi-stage serial centrifugal cold compressors, the...

A thermal multi-zone model is used to describe the self-pressurization process in a liquid helium storage tank. This model divides the liquid and ullage of the tank into multiple zones taking into account the effects of the boundary layer in each zone. Combined with helium property parameters from REFPROP, the model can calculate the self-pressurization process of a liquid helium storage tank...
