The unsteady response of a flame to acoustic or flow perturbations plays a crucial role in
thermoacoustic combustion instability. The majority of studies on this subject presents and …

Open-loop control of self-excited flame pulsating oscillations and thermo-acoustic instability
is considered in this work. The performance of the control strategy is numerically evaluated …

The present work compares the respective advantages and disadvantages of compressible
and incompressible computational fluid dynamics (CFD) formulations when used for the …

Abstract Large-Eddy Simulation (LES) is combined with advanced System Identification (SI)
to simultaneously infer models for the source of combustion noise and the dynamic …

Combustion instability can lead to high amplitude oscillations of pressure in the combustion
chamber, which would seriously affect the normal operation of the combustion system. In …

The response of a laminar lean premixed flame to excitations based on its position in the
combustion chamber and the stability of a burner are numerically investigated. A finite …

This paper investigates the linear thermoacoustic dynamic response of laminar premixed
stoichiometric propane/air flames under different oncoming flow velocity profiles …

The acoustic field of a turbulent lean cpremixed open flame is numerically investigated by a
hybrid method solving the Navier-Stokes equations in a large-eddy simulation formulation …

In this paper, the effect of the swirler scheme on combustion instability is studied. Through
the proper orthogonal decomposition (POD) of flame images, Abel inverse transform and …

This paper presents a method for predicting the stability boundaries of a model combustion
chamber using a data-driven approach based on the n-τ model. The n-τ model is derived …
