A rotary jet expander (RJE) achieves low temperature 2 ~.~ ~] ] ~ refrigeration based on the cooling effect of wave expansion after rapidly filling a tube with a compressible fluid, The transient performance in pulse tubes is one of the most important influences on the isentropic efficiency of b 2r b a RJE, and it depends on the pulse frequency, time Figure1 Series of operations of the RJE. 1,Enter-pipe; 2, jet; 3, matching in one pulse period and transient heat transfer, pressure pulse tube bunch; 4, out pipe; 5, hollow axle with jets. Work on this transient performance proved that opti-(See Nomenclature for explanation of symbols) mization of parameters for high isentropic efficiency in RJE could be achieved.
