Abstract
Turbomachinery has been given serious consideration for miniature cryogenic refrigerators because of the inherent reliability and long life of this class of machinery. Maintenance intervals and time between overhauls can be as much as an order of magnitude greater than piston machinery in similar applications. Turbocompressors and turbines are, however, normally considered only as high-volumetric-flow devices. The efficiency of both turbines and compressors is a function of the specific speed.
