  1. 393. A Computational Approach of 1D and 2D/3D CFD Coupled Model
    Tao Fang (Georgia Institute of Technology)

    Contributed Oral Presentation

    The physics behind Stirling-type cryocoolers are complicated. One dimensional simulation tools only offer limited details and accuracy, in particular for cryocoolers that have non-linear configurations. Multi-dimensional Computational Fluid Dynamic (CFD) methods are useful but are computationally expensive in simulating cyrocooler systems in their entirety. In view of the fact that some...

  2. 465. Role of Size on the Relative Importance of Fluid Dynamic Losses in Linear Cryocoolers
    Dr Carl Kirkconnell

    Contributed Oral Presentation

    Thermodynamic and fluidic modeling results for a novel small satellite (SmallSat) Stirling Cryoooler, capable of delivering up to 400 mW net cooling power at 80 K for less than 6 W DC input power, are discussed in this paper. Industry and government requirements for SmallSat borne infrared sensors is driving the development of ever-more miniaturized cryocooler systems. Such cryocoolers must...

  3. 99. Performance improvement in a Stirling cooler with Methane as a condensable component in Helium-Methane mixture as working fluid for refrigeration temperature about 130 K
    Prof. Shridhar Bapat (Professor, Department of Mechanical Engineering, Indian Institute of Technology Bombay, Mumbai, India)

    Contributed Oral Presentation

    Methane is one of the major volatile components of the natural gas. With the heat load, the low boiling components tend to evaporate first and is likely to build up the pressure in the storage vessel. In order to avoid such situation, the storage vessel is generally vents out the vapour to the atmosphere. If this vapour can be re-condensed in-situ at storage pressure, it will save Methane from...

  4. 440. Acoustic field characteristics in a free piston Stirling cryocooler with high cooling capacity
    Dr Guoyao Yu (Key Laboratory of Cryogenics, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences)

    Contributed Oral Presentation

    High cooling power (i.e., from several hundred Watt to thousand Watt) free piston Stirling cryocooler could find important application in fields such as boil-off gas recondensation and superconducting. This work reveals the acoustic field characteristics mainly concerning the regenerator and acoustic impedance match between cooler and linear compressor. Based on thermoacoustic theory,...

  5. 25. A Performance Analysis on Free-piston Stirling Crycooler based on an Idealized Mathematical Model
    Yongxiang Guo (Zhejiang University)
    12/07/2017, 12:00
    Contributed Oral Presentation

    Free-piston Stirling crycooler, featuring its elimination of the motor that drives the displacer, has extensive applications in various areas for its simplicity in structure and decrease in mass. However, the elimination of the motor has not only added to the complexity of its analysis and design, but also made it differ from Stirling cryocoolers with displacer driving mechanism, such as the...
