摘要:
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.

Systems, methods and apparatus for providing an electromagnetic flow controller. In one embodiment, an electromagnetic flow controller can have two substrates, a permanent magnet, and two electrical traces. One of the substrates may deflect away from the other substrate upon applying an electrical signal to at least one of the two electrical traces.
