| Abstract: | A simulation has been performed on a standing wave thermoacoustic engine with gas-liquid coupled oscillation,by introducing a liquid piston ofEMIM]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. |

| Keywords: | thermoacoustic engine liquid piston ambient temperature ionic liquid |
