摘　　要：采用分布参数法,以行波型热声发动机网络模型为例进行了数值模拟计算,计算所用模型与实验模型具有相同的结构尺寸以及运行工况。计算以线性热声理论为基础,通过MATLAB编程,成功得到了整个热声系统的压力和体积流率分布状况,继而计算出了声功流的分布。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.
