Abstract: In this paper, the numerical simulation, which was illustrated by the case of the network model of travelling-wave thermoacoustic engine, was calculated by using distributed parameter method, and the construction dimension and operation condition of calculation model run parallel with experimental model. Based on linear thermoacoustics, it succeeded in obtaining the status of fluctuating pressure amplitude and volumetric flow rate amplitude in the thermoacoustic system through MATLAB programming. Then, the acoustic power flow amplitude was also calculated.

Key words: distributed parameter method, network model, thermoacoustic engine
