      Cao, H. S.; Lerou, P. P. P. M.; Mudaliar, A. V.; Holland, H. J.; Derking, J. H.; Zalewski, D. R.; ter Brake, H. J. M. (Georgia Institute of TechnologyICC Press, 2008-05)
      Microcoolers machined from glass wafers based on Joule-Thomson (J-T) expansion have been investigated for many years at the University of Twente. After successful development of singlestage J-T microcoolers with a cooling ...
    • Development of a Miniature Fast Cool Down J-T Cryocooler 

      Tzabar, N.; Lifshits, I. (Georgia Institute of TechnologyICC Press, 2008-05)
      One major advantage of Joule-Thomson (J-T) cryocoolers over other cryocoolers is the ability to achieve a very fast cool-down, in the range of only a few seconds. The main fluid is chosen according to the desired cooling ...
    • Effect of Heat Exchanger Configuration on the Performance of Joule-Thomson Refrigerators 

      Hong, Yong-Ju; Park, Seong-Je; Choi, Young-Don (Georgia Institute of TechnologyICC Press, 2008-05)
      A typical Joule-Thomson (J-T) refrigerator consists of a recuperative heat exchanger, a gas expansion nozzle, a mandrel, and a compressed gas storage bottle. The thermodynamic performance of a J-T refrigerator depends ...
    • Open Cycle Joule-Thomson Cryocooling by Mixed Coolant 

      Maytal, B-Z. (Georgia Institute of TechnologyICC Press, 2008-05)
      Mixed coolants are conventionally employed for the closed cycle Joule-Thomson mode of cryocooling. Here, the potential of mixed coolants is utilized for reducing the pressure of operation. Numerous experimental and theoretical ...
