TL;DR: In this article, an isothermal model for pulse tube refrigerators is introduced, based on the premise that a pulse tube refrigerator can be considered to be a type of split Stirling refrigerator, and the gas in the pulse tube can be divided into three parts.

TL;DR: An improved numerical modeling technique for predicting the detailed performance and characteristics of an orifice pulse tube refrigerator has been developed in this paper, where a variety of physical factors such as gas flow friction, heat transfer in the heat exchanger and regenerator, real material properties etc., are included in order to improve the accuracy of the model.

TL;DR: A numerical model of a double-inlet pulse tube refrigerator (DPT) has been developed and the equations of continuity, momentum and energy (for both gas and solid) are solved numerically as discussed by the authors.

TL;DR: In this article, a modified orifice pulse tube refrigerator (MOPTR) without a reservoir is proposed, where the crankcase of the compressor is used instead of the reservoir to bring about the appropriate phase shift between the pressure and the flow velocity in the pulse tube.

TL;DR: In this article, a double-inlet reversible pulse tube refrigerator (DRPTR) is proposed and two important parameters which affect the performance of the DRPTR are discussed.
