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.

What is claimed is: 1. A method of analyzing combustion dynamics of a combustor system in the time domain, the combustor system including an inlet pipe coupled in flow communication with a combustion chamber, said method performed by a combustion dynamics analysis system (CDAS) including the steps of:determining, using the CDAS, a characteristic equation of a wave traveling in the inlet pipe;determining further an acoustic pressure oscillation in the combustion chamber;determining further a pressure fluctuation in the inlet pipe using the characteristic equation and the determined acoustic pressure oscillation; andoutputting the determined pressure fluctuation to at least one of a database and a display.
