| Abstract: | 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. |
