Acoustic Design Parameter Change of a Pressurized Combustor Leading to Limit Cycle Oscillations
When aiming to cut down on the emission of nitric oxides by gas turbine engines, it is advantageous to have them operate at low combustion temperatures. This is achieved by lean premixed combustion.

On singularities and instability of reconstruction in thermoacoustic tomography
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.

Review of acoustic field effects on flame dynamics and combustion applications
Acoustic-flame coupling technology is an interdisciplinary frontier field investigating the complex interactions between sound waves and combustion. Generally, the acoustic field can be divided into two modes based on its relative position to the flame ...

Causality and intrinsic thermoacoustic instability modes
Direct numerical simulation of a confined laminar premixed flame has been performed in an anechoic combustor, showing self-sustained intrinsic thermoacoustic oscillations. Theoretical predictions based on acoustic jump relations and the n − τ model for the flame are presented and causality concerns are discussed.
