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.
Abrupt changes in the state of a system are often undesirable in natural and human-made systems. Such transitions occurring due to fast variations of system parameters are called rate-induced tipping (R-tipping). While a quasi-steady or sufficiently slow variation of a parameter does not result in tipping, a continuous variation of the parameter at a rate greater than a critical rate results in tipping.
