Vibro-acoustic coupling is essential in many industries, such as automotive, aerospace, nuclear, and construction. Vibro-acoustic coupling can cause acoustic instability and fatigue, resulting in severe damage to the system. During combustion, the fluctuations of flame emerge in acoustic waves; the sound waves impact the chamber's walls and ...
