摘要
对热声系统的起振与消振行为进行了实验研究 ,发现存在热声振荡滞后回路。研究了不同加热方式 (对称加热与单向加热 )及充气压力对滞后回路的影响 ,得出一些令人感兴趣的结论。
A hysteretic loop,a special loop due to the difference between the onset temperature and the damping temperature,is proposed in the thermoacoustic oscillation for the first time.It is confirmed by the experiments on a thermoacoustic prime mover with nitrogen as the working fluid.The influence of pressure and heating on the hysteretic loop is also investigated and some interesting results are presented.
