ABSTRACT:
Methods and systems for analyzing combustion dynamics of a combustor system in the time domain are provided. The combustor system includes an inlet pipe coupled in flow communication with a combustion chamber. The method includes determining a characteristic equation of a wave traveling in the inlet pipe, determining an acoustic pressure oscillation in the combustion chamber, and determining a pressure fluctuation in the inlet pipe using the characteristic equation and the determined acoustic pressure oscillation.
