Title: A THERMALLY EFFECTIVE REGENERATOR FOR LOW TEMPERATURE CRYOCOOLERS
Agency: NASA
Contract: N/A
Award Amount: $491,273.00
 

Abstract:

SMALL STIRLING CRYOCOOLERS ARE LIMITED IN THE ATTAINMENT OF VERY LOW TEMPERATURES BY THE ADVERSE TREND IN THE RATIO OF VOLUMETRIC HEAT CAPACITY BETWEEN GASEOUS HELIUM AND REGENERATOR MATRIX MATERIALS BELOW ABOUT 40 K. THE PROPOSEDCONCEPT FOR A THERMALLY EFFECTIVE REGENERATOR OVERCOMES THISLIMITATION BY PROVIDING A DYNAMIC HELIUM MATRIX. THE OBJECTIVE OF THE PHASE I PROJECT IS TO EXPERIMENTALLY DEMONSTRATE THE RELATIVE THERMAL STORAGE EFFECTIVENESS OF THIS REGENERATOR CONFIGURATION AND A MORE CONVENTIONAL REGENERATOR BETWEEN 4.2 K AND 77 K. THE EFFORT INCLUDES DESIGN, FABRICATION AND TESTING OF AN INNOVATIVE REGENERATOROVER A RANGE OF MASS FLOWS, PRESSURES, AND OPERATING FREQUENCIES. RESULTS WILL BE DOCUMENTED IN A FINAL REPORT.
