| 摘 要： | 本文针对一台气液耦合振动热声发动机，以1．5kg的水作为液柱，以氮气、氦气、氩气和二氧化碳分别作为气体工质，在2．0MPa平均工作压力下，实验对比了不同气体工质对谐振频率、压力振幅和板叠热端温度等系统性能参数的影响。实验结果表明，在相同加热功率下，采用氩气的系统获得的压力振幅最大；而在相同板叠热端温度下，以二氧化碳为气...

| Abstract: | This paper focuses on a thermoacoustic engine with gas and liquid,constructed by introducing a 1.5 kg water column into the U-shaped resonant tube.The impact of different working gases,i.e.,nitrogen,helium,argon,and carbon dioxide,on the resonant frequency,pressure amplitude, and hot end temperature of stack in such an engine are studied experimentally.The experimental data indicate that the argon-water system can achieve the highest pressure amplitude at a given heating power,while for a certain hot end te... |
