This paper is a continuation of our work on the thermodynamical aspects of pulse tubes. This time we discuss various flow- (or pressure) controlling devices, proposed to improve the performance of pulse tube refrigerators (PTR), such as orifice, expander, four-valve method, inertance tube, and first and second inlet. We have obtained analytical expressions for the various cases assuming a finite flow resistance in the regenerator, but with zero void volume, perfect heat exchange, and high heat capacity of the regenerator material.
