| 摘 要： | 实验研究了热声发动机起振过程中典型的非线性现象,即双阈起消振现象。实验结果表明,充气压力以及加热功率对于双阈起振现象有着明显的影响,而双阈消振现象则主要由充气压力和消振时刻系统压力振幅决定。该研究有助于增进对热声振荡现象的进一步理解与认识。

| Abstract: | The typical nonlinear phenomena,i.e.double-threshold effect mode,was studied experimentally in this paper.The results show that the influence of the charging pressure and heating power on the double-threshold onset process is significant.The double-threshold damping process is dependent on the charging pressure and pressure amplitude at the time of damping.This study will contribute to further understanding of the thermoacoustic oscillation. |
