Ejectors have been used for many years near ambient temperature in both refrigeration equipment and chemical processing equipment. It was only recently, however, that Rietdijk [1] proposed the use of an ejector in cryogenic refrigerators. Most of the work on cryogenic ejectors reported previously [1–3] used helium as the working fluid. The experimental performance data presented here are believed to be the first reported using low-temperature nitrogen and are the most extensive reported for any cryogenic fluid.
