Thermoacoustic instability is a flow instability that arises due to a two-way coupling between
acoustic waves and unsteady heat release rate. It can cause damaging, large-amplitude …

Dynamical systems theory has emerged as an interdisciplinary area of research to

We take a complex systems approach to investigating experimentally the collective
dynamics of a network of four self-excited thermoacoustic oscillators coupled in a ring. Using …

The prediction of self-excited combustion instabilities in a can-annular gas turbine
combustion system is a significant challenge, mainly because the instabilities originate from …

Longitudinal-mode combustion instabilities in can-annular gas turbine combustion systems
are influenced by acoustic interactions between adjacent combustors; these interactions …
