Étude par analogie électrique de différents types de tubes à gaz pulsé : modélisation et expérience

Comparison of two models of a double inlet miniature pulse tube refrigerator: Part B electrical analogy

“…This basic idea is presented in [9] for the Orifice Pulse Tube Refrigerator (OPTR), it seems that it has been first introduced in France by researchers of the Ecole Nationale Supérieure [10,11]. Despite the previous part indicates that pressures variations are not purely sinusoidal, this assumption is admitted.…”

“…This modeling principle developed by the authors is specially applicable to miniature systems and consists in establishing an analogy with electric circuits only composed of resistances, capacities and inductances.

“…In spirit of more important popularization this point of view leads naturally to introduce the use of simple equivalent electric scheme. So because the described devices operate in periodic regime, their action can be assimilated to that of an electric quadripole constituted of resistances, capacities and inductances [9,10,11]. This remark is exploited in this second part of the research.…”
