Two kinds of representative CC-Repowering (feed water heating repowering,full firing repowering) were analyzed and compared in this paper. Aremarkable phenomenon was observed: Efficiency monotonouslychanges with work-ratio in FF-Repowering system; but in FWH-Repoweringsystem, there exists an optimal ratio at which point the efficiency isthe highest. Another phenomenon to be paid attention is that under somework-ratio, the efficiency of FWH-Repowering is higher than that ofFF-Repowering, giving rise to correcting the conventional concept.

The oscillation performance of jet, as oscillation frequency, is the essential data for designing the fluidic device, which is also the key factor that influence the coupling effect of fluidic device and receiving tube. This paper does experiment on the oscillation availability and frequency of feedback jet-oscillation gas wave refrigeration. As a conclusion, the jet oscillates only in a certain range of geometrical sizes and operating conditions. Under the condition of high pressure ratio, the frequency of the jet"s oscillation is only affected by the feedback tube"s length and chamber remarkably. Under the condition of low pressure ratio, the frequency descends with rise of the pressure ratio.

本文将跨音速正反馈射流振荡器与接受管耦合，对耦合后的射流振荡气波制冷机的可振性、振荡频率以及它们的影响因素作了实验研究，得出如下结论：射流只在一定的操作条件和几何结构尺寸范围内才能稳定振荡；射流的振荡频率在较高压比下只受反馈管长和反馈管容腔大小的显著影响，在小压比下随压比的增大而增加；其它结构尺寸和操作条件只影响可振性。
