| Outline of Final Research Achievements |
Thermoacoustic oscillations mean thermally-induced acoustic oscillations of a gas column. Understanding their nonlinear behaviors should lead to the development of various applications like acoustic heat engines and suppression tools of combustion instability.
In this study, mutual interactions between thermoacoustic oscillators were introduced by using a connecting tube and a valve to successfully observe synchronization and oscillation-death phenomena.
Also, chaos-chaos synchronization was demonstrated for the first time in the coupled thermoacoustic oscillators.
