It is accepted that the thermoacoustic behavior of a given combustion system can be
analyzed by investigating how its natural acoustic modes are perturbed by the flame …

Can-to-can acoustic interactions in a circumferential network of lean-premixed combustors
have a prominent role in the development of complicated modal dynamics and large-scale …

Can-annular combustors are equipped with a set of nominally identical cans,
circumferentially arranged around the shaft. Adjacent cans are coupled acoustically via a …

We investigate the low-order modeling of collective dynamics in a can-annular combustor
consisting of four ring-coupled turbulent lean-premixed combustors. Each combustor is …

In can-annular combustors, a narrow can-turbine junction leads to an acoustic coupling
between the cans, yielding unique features that greatly impact the (thermo) acoustic …

Thermoacoustic systems can exhibit self-excited instabilities of two nature, namely cavity
modes or intrinsic thermoacoustic (ITA) modes. In heavy-duty land-based gas turbines with …

This numerical study examines the pressure amplitude distribution, focusing on amplitude
death, in a ring-coupled network of nonlocally coupled asymmetric thermoacoustic …

Can-annular combustors feature clusters of thermoacoustic eigenvalues, which originate
from the weak acoustic coupling between coupled oscillators. Each oscillator represents the …

Thermoacoustic instabilities arise from the feedback between an acoustic field and the
unsteady heat released in a burner, yielding self-sustained oscillations. A fundamental …

Heavy-duty land-based gas turbines with can-annular combustors typically exhibit a set of
thermoacoustic modes with similar frequencies, due to their rotational symmetry and the …
