On the oscillating flow characteristics of cryocooler regenerator at low temperatures.

Author(s) : SHEN Q. Q., JU Y. L.

Summary

In this paper, the authors present a brief review of their previous experimental results and correlations on the friction factor of cryocooler regenerators operating at oscillating flow and pulsating pressure conditions, for different mesh sizes of packed woven-screens, focusing on the effects of different operating frequency ranging from 20 to 80 Hz, at room and cryogenic temperatures. The comparison of their friction factor data with those of other research is presented to clarify the reason for their difference and a discussion on a new oscillating flow correlation of regenerator, in terms of several non-dimensional parameters, is given and compared with others.
