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 …

Described are sub-scale tests that successfully demonstrate active feedback control as a
means of suppressing damaging combustion oscillations in natural-gas-fueled, lean-premix …

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 …

This paper presents the results of an investigation of active control of combustion instabilities
in a natural gas, high-pressure, full-scale gas turbine combustor that was retrofitted with an …

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 …

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 …

The thermoacoustic response of an industrial-scale gas turbine combustor to fuel flow
perturbations is examined. Experimental measurements in a laboratory combustor along …
