摘要
基于热声理论,介绍了一种相对于传统热声振荡演示器更为简单、有效、直观的热声振荡演示装置,该装置除可调节声波振幅外,还可以调节声波的频率。该装置有助于更好地理解热声效应,了解影响热声振荡的因素,为进一步的深入研究奠定基础。
A novel thermoacoustic oscillation demonstrator was designed and constructed based on the thermoacoustic theory.Compared with the traditional ones,the demonstrator is simpler and more effective.Thermoacoustic oscillation occurs in 10 minutes.Both the acoustic amplitude and the frequency can be adjusted.The thermoacoustic demonstrator is helpful for the understanding of the thermoacoustic oscillation and can offer reference for further study of the thermoacoustic effect.
