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 …

This paper utilizes Cauchy's argument principle in the frequency domain to develop novel
stability maps, providing guidelines for measures which can be taken to mitigate …

The Galerkin modal expansion is a well-known method used to develop reduced order
models for thermoacoustics. A known issue is the appearance of Gibbs-type oscillations on …

This work presents a data-driven optimization technique for the optimization of the flame
response within a low-order acoustic network model. The methodology exploits the Nyquist …

Thermoacoustic systems are often modeled with a hybrid approach that combines separate
models for acoustic propagation and flame dynamics. Model Order Reduction (MOR) may …

Low-order network models, commonly used to assess the thermo-acoustic stability of
combustors, can be cast in a linear, time-continuous state-space representation. A standard …
