A Heat-Balance Analysis of a Gifford-McMahon Cryorefrigerator
In reciprocating cryorefrigerators using small thermal regenerators such as the Stirling-cycle, Vuilleumier-cycle, Solvay-cycle, and Gifford-McMahon-cycle devices, performance is a very complicated function of many variables. Even for the simplest single-stage systems, the number of variables is about twenty-five. Also, in making any performance calculation, one has to make a large number of assumptions or approximations.
