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 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 …

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 …

Thermoacoustic instabilities in stationary gas turbines may cause high-amplitude limit
cycles, leading to damaged components and costly down-time. To better understand the …

We experimentally study the effect of rotational asymmetries in the flame response
distribution on the thermoacoustic oscillations of four turbulent lean-premixed combustors …

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 …

Heavy-duty land-based gas turbines are often designed with can-annular combustors, which
consist of a set of identical cans, acoustically connected on the upstream side via the …

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 …

Can-annular combustors can feature azimuthal instabilities even if the acoustic coupling
between the individual cans is weak. Recently, various studies have focused on modeling …

Networks of coupled nonlinear oscillators model a broad class of physical, chemical and
biological systems. Understanding emergent patterns in such networks is an ongoing effort …
