| 中文摘要: |
| Wave rotor is an unsteady flow device in whose passages pressured streams directly contact and exchange the energy due to the movement of pressure waves. A novel refrigeration apparatus named pressure exchanging refrigerator (PER) is developed by using four-port through flow (TF) wave rotors. The operating procedure and refrigeration principle are investigated based on one-dimensional unsteady flow theory, and the fluidic behavior of PER is also analyzed by means of computational fluid dynamics (CFD). A basic limitation relation with main structural parameters and operating parameters is deduced. Most main influencing factors are studied by experiments. The isentropic efficiency now can get 68%. The results show that wave rotors used for refrigeration technology are feasible and promising in pressured gas refrigeration cases. |
