RISOptical Transfer Function Measurements for Technically Premixed Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with a novel approach for measuring thermoacoustic transfer functions. These transfer functions are essential to predict the acoustic behavior of gas turbine combustion systems. ...
Thermoacoustic Modeling of a Gas Turbine Combustor Equipped With Acoustic Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the TA3 thermoacoustic network is presented and used to simulate acoustic pulsations occurring in a heavy-duty ALSTOM gas turbine. In our approach, the combustion system is ...
Thermoacoustic Modeling of a Gas Turbine Using Transfer Functions Measured Under Full Engine Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermoacoustic transfer functions of a full-scale gas turbine burner operating under full engine pressure have been measured. The excitation of the high-pressure test facility was done using a ...
Phase-Resolved Laser Diagnostic Measurements of a Downscaled, Fuel-Staged Gas Turbine Combustor at Elevated Pressure and Comparison to LES Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A technical gas turbine combustor has been studied in detail with optical diagnostics for validation of large-eddy simulations (LES). OH* chemiluminescence, OH laser-induced fluorescence (LIF) and ...
