Unsteady flow; Wave rotor refrigerator; Hydrated operating performance

Because of bilateral pulse tubes, wave rotor refrigerators (WRRs) have excellent fluidic operation performance. In this work, a WRR experimental rig with throughput of 3x104Nm3/d and expansion ratio 3 for hydrated gases has been built. A number of experiments show that the temperature of low pressure port of WRR has little influence on refrigeration efficiency. This makes possible of maintaining excellent refrigeration efficiency when WRR operating with high-liquid gases. Actual liquid experiments do show the excellent fluidic operation performance: the refrigeration performance remains almost unchanged even if WWR operates with 13.7 %(w) liquid ratio.
