This paper examines the effects of steady-state and transient hydrogen enrichment on
thermoacoustic instability in a model gas turbine combustor. Combustion instability, a …

Low-emissions gas turbine combustion, achieved through the use of lean, premixed fueling
strategies, is susceptible to combustion instability. The driving mechanism for this instability …

To achieve decarbonization in power-generating gas turbines, the technology of mixing
hydrogen with natural gas is garnering significant attention. However, when blending natural …

Combustion instability in gas turbines is often mitigated using fuel staging, a strategy where
the fuel is split unevenly between different nozzles of a multiple-nozzle combustor. This work …

The characterization and mitigation of thermoacoustic combustion instabilities in gas turbine
engines are necessary to reduce pollutant emissions, premature wear, and component …

Fuel staging is an effective way to attenuate combustion instability in lean, premixed
combustion systems. Combustion instability occurs due to the coupling between heat …

In this work, we quantify the level of variation in unstable combustion oscillation amplitudes
and identify the source of this variation in a multi-nozzle can combustor. At conditions where …

Modern gas turbine engines are typically operated in a lean-premixed configuration in order
to meet emissions requirements. Lean operation makes gas turbines more susceptible to …

This paper examines the effects of steady-state and transient hydrogen enrichment on
thermoacoustic instability in a model gas turbine combustor. Combustion instability, a …

This dissertation examines the model-based optimization of sensor placement, estimation,
and control for the active suppression of thermoacoustic instabilities in a one-dimensional …
