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 …

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 …

The higher demand for temperature rises and low-pollution combustion methods make it
more problematic to regulate the outlet temperature distribution (OTD) of advanced gas …

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 …

Effects of secondary gas injection on flame shape and combustion stability of a premixed
swirl methane/air flame were investigated experimentally. Without secondary gas injection …

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 …

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

Dry low emissions (DLE) systems are well-known to be susceptible to thermoacoustic
instabilities. In particular, transverse, spinning modes of high frequency may appear, and …

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

The emergence of collective dynamical behaviors in a complex system has distinct
properties that its individuals do not have on their own. In the study, a series of circular …
