【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][BF₄]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。更多还原

【Abstract】 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.更多还原
