摘　　要：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 thermoacoustic engine with gas-liquid coupled oscillation, by introducing a liquid piston of [EMIM][BF4]. 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.
