Thermoacoustic instability for chemically reacting flows was investigated using large eddy simulations coupled with a lookup table for turbulence-chemistry closure. The onset of instability was evaluated from pressure fluctuations, as well as standard and extended Rayleigh criterion, as suggested in...
