In the present work, an atmospheric pressure combustor using a modern aviation gas
turbine fuel nozzle was used to demonstrate active combustion control. The combustor …

High-bandwidth fuel modulation is currently one of the most promising methods for active
combustion control. To attenuate the large pressure oscillations in the combustion chamber …

A study has been performed to evaluate the effectiveness of a closed-loop control system to
suppress thermo-acoustic combustion instabilities. The pulsewidth modulation technique …

A number of recent articles have demonstrated the use of active control to mitigate the
effects of combustion instability in afterburner and dump combustor applications. In these …

Active combustion control has been accomplished in many laboratory and real-world
combustion systems by fuel modulation as the control input. The modulation is commonly …

Active combustion control has been accomplished in many laboratory and real-world

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 …

The present paper describes an active control system consisting of a fast-acting actuator
valve, coupled with a control algorithm capable of adaptive phase and amplitude control for …

In this study, an internal feedback mechanism capable of sustaining high amplitude/low
frequency combustion instabilities was explored in a 90 degree sector of an advanced gas …

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 …
