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

This thesis describes an experimental investigation of the flame transfer function between
flow disturbances and heat release oscillations in lean, premixed combustors. This research …

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 …

Measurements of vibration and combustion chamber dynamic pressures have been taken
on a number of 150MW industrial gas turbines operating on pre-mixed natural gas, both …

This paper demonstrates cross-frequency coupling between pressure, heat release rate, fuel
spray and velocity oscillations in a model aeronautical gas turbine combustor operating at a …

A method to predict the thermoacoustic behavior of gas turbine combustion chambers with
premixed, turbulent, swirl-stabilized flames is presented. The combustion system is …

We report the design and operation of a test device suitable for studying combustion
oscillations produced by commercial-scale gas turbine fuel nozzles. Unlike conventional test …

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 framework is presented for analyzing the local instantaneous phase difference between
non-stationary heat release rate and pressure oscillations that is appropriate for use in high …
