进行了气液耦合振动驻波型热声发动机定量模拟.重点比较分析了单纯气体振动系统和引入[EMIM][BF_4]室温离子液体作为液体活塞的气液耦合振动系统的运行参数,并考察了液体活塞的质量对热声发动机谐振频率、压力振幅以及板叠热端温度等的影响.
A simulation has been performed on a standing wave tliermoacoustic engine with gas-liquid coupled oscillation,by introducing a liquid piston of[EMIM][BF_4].According to the simulation,the operating parameters with and without the liquid piston are compared and analyzed in details.The effects of liquid piston mass on resonant frequency,pressure amplitude,and hot-end temperature of stack are discussed.
