Article Synopsis
- The study introduces a framework using Lagrangian Coherent Structures (LCSs) for controlling tonal sounds caused by thermoacoustic instability in a turbulent combustor.
- Researchers performed experiments to identify dynamic flow regions where dominant acoustic frequencies occur, revealing critical interactions between shear layers and vortices in the combustor.
- A passive control strategy was developed by injecting secondary air to influence the shear layer's behavior, effectively reducing sound amplitude by preventing vortex impingement on the combustor walls.
