This paper describes the application of active, open loop, control in effective damping of
severe (ie, peak to peak pressure amplitudes of up to 35 psi relative to a mean combustor …

This paper describes the application of active, open loop, control in effective damping of
severe combustion instabilities in a high pressure (ie, around 520 psi) gas turbine …

Emphasis on reducing the levels of pollutants created by gas turbine combustors has led to
the development of lean, premixed combustor designs, especially for industrial applications …

This paper describes the application of active, open loop, control resulted in effective
damping of severe (ie, peak to peak pressure amplitudes of up to 60 psi relative to a mean …

Stringent emissions requirements for stationary gas turbines have produced new challenges
in combustor design. In the past, very low NOx pollutant emissions have been achieved …

Combustion dynamics is a prominent problem in the design and operation of low-emission
gas turbine engines. Even modest changes in fuel composition or operating conditions can …

Combustion instabilities in modern high-performance propulsion systems are often
manifested as large amplitude pressure oscillations and can result in serious performance …

This paper describes a study of open loop control of combustion instability employing
harmonic fuel injection rate modulation at a non-resonant frequency. It's shown that this …
