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 …

Thermoacoustic interactions in a circumferential network of lean-premixed combustors have
a substantial impact on engine-level dynamics in a can-annular gas turbine combustion …

Thermoacoustic instabilities in can-annular combus-tors of stationary gas turbines lead to
unstable Bloch modes which appear as rotating acoustic pressure waves along the turbine …

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 paper presents a thermoacoustic model in the frequency domain for multi-burner
combustors composed of multiple plenum-nozzle-chamber modules with cross-talk at both …

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

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 …

In the literature on thermoacoustic instabilities in combustors, a distinction is typically made
between annular and can-annular systems because these are the most common gas turbine …
