The network model of thermoacoustic engine and its simulation method are introduced. The developed calculation program can predict the acoustic field of the thermoacoustic system, the impedance of the components such as the regenerator and the system as well as the performance parameters including the cooling capacity, cooling temperature, heat flow, sound power and COP. The simulation study of this model will provide the premise and basis for the optimal design of thermoacoustic system.
