Thermoacoustically driven flame motion and heat release variation in a swirl-stabilized gas turbine burner investigated by LIF and chemiluminescence [PDF]
, 2018 Laser-induced fluorescence and chemiluminescence, both phase-locked to the dominant acoustic oscillation, are used to investigate phenomena related to thermoacoustic instability in a swirl-stabilized industrial scale gas turbine burner.

Uncertainty Management in Thermoacoustic Instability Analysis [PDF]
, 2021 The present thesis focuses on developing a comprehensive uncertainty management framework for quantifying and mitigating the thermoacoustic modal instability risk. Advanced dimensionality reduction and surrogate modeling strategies are proposed, which allow efficiently and accurately handling high-dimensional uncertain inputs.

On singularities and instability of reconstruction in thermoacoustic tomography
, 2009 We consider the problem of thermoacoustic tomography (TAT), in which one needs to reconstruct the initial value of a solution of the wave equation from its value on an observation surface. We show that if some geometric rays for the equation do not intersect the observation surface, the reconstruction in TAT is not Hölder stable.

Characterization and Simulation of the Thermoacoustic Instability Behavior of an Advanced, Low Emissions Combustor Prototype [PDF]
Extensive research is being done toward the development of ultra-low-emissions combustors for aircraft gas turbine engines. However, these combustors have an increased susceptibility to thermoacoustic instabilities.
