The thermoacoustic coupling oscillation (TACO) of combustion is a syntonic phenomenon

which often occurs between the heat release pulsation of flame and the inherent acoustic pulsation of combustion chamber. TACO exerts significant influence on the stability and performance of the combustion system

which can lead to the component fatigue in low-cycle or high-cycle

the flame instability and flame-out

and even fatal damage to the combustion chamber. This paper aims to systematically grasp the development process of TACO and point out the direction for further research. This study introduces the formation mechanism of TACO based on its fundamental process

and then summarizes the representative works on TACO from perspectives of the theoretical analyses

numerical simulations

experimental researches

and control methods. Finally

the challenges and future directions of TACO applications are pointed out. Further research on TACO should focus on improving the nonlinear thermoacoustic theory

constructing multi-scale models

and developing acoustic suppressors with adaptive suppression functions.
