| 摘 要： | 以热声发动机为例采用网络模型计算了热声热机系统的振荡频率，得出振荡频率为复频率，其实部代表实际频率，虚部表示压力幅值的衰减程度。对热机系统在各种不同的情况下(包括不同大小的谐振腔、板叠间距、气体静压、系统长度)进行了数值计算，理论计算值与实验结果能很好的吻合。 |

| Abstract: | The network model is used to calculate oscillation frequency of thermoacoustic prime mover.Frequency theoretically calculated by the model is plural,whose real part denotes actual frequency of the system and imaginary part means attenuation coefficient of acoustic pressure.Numerical calculation is made under different conditions including different resonance cavities,gaps between each parallel plate,gas pressures and system lengths.Frequency theoretical calculated and frequency experimentally measured are in good agreement. |
| Keywords: | thermoacoustic engine regenerator network model oscillating frequency |
