气波转子是利用气波来传递能量的一种压力交换装置,已成功应用于内燃机及燃气轮机上.为研究通流式(through-flow,TF)气波转子特性,重新设计了定子,搭建了试验台架,并完成了TF气波转子的性能台架试验.进行了不同转速、不同温度、不同压力工况下的性能试验.结果表明,提高气波转子能量入口处的压力和温度有利于提高其性能,TF气波转子的最佳转速为13 000 r/min左右.试验结果表明该TF气波转子结构基本合理,能提高进气压力,最大压比可达2.0.
Gas-wave rotor is a kind of pressure exchange device that uses gas wave to transfer energy and has been successfully applied to internal combustion engine and gas turbine.In order to study the characteristics of through-flow (TF) gas-wave rotor, the stator was redesigned to build The test bench and the performance bench test of the TF air-cooled rotor were completed.The performance tests under different rotational speed, different temperature and different pressure conditions were carried out.The results show that increasing the pressure and temperature at the inlet of the air-wave rotor is beneficial to The optimum speed of the TF air-cooled rotor is about 13 000 r / min.The experimental results show that the structure of the TF air-cooled rotor is basically reasonable and can increase the air inlet pressure with a maximum pressure ratio of up to 2.0.
