RISInvestigations on Thermodynamic Processes of a Novel Pneumatic Drive Asymmetric Gifford-McMahon Cycle Cryorefrigerator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a numerical and experimental investigation is conducted on a novel pneumatic-drive asymmetric Gifford-McMahon cycle cryorefrigerator (GMCR). In the pneumatic-drive asymmetric Gifford-McMahon cycle cryorefrigerator, ...
Rotational Effect on Flow Field and Thermal Characteristics of a Turboexpander for Helium Liquefaction System: A Numerical Perspective
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cryogenic turboexpander is an essential component to produce the refrigeration effect in various helium liquefaction systems. The convergent nozzle and small-scale radial inflow turbine (turboexpander) are the important ...
