From Pressure Time Series Data to Flame Transfer Functions: A Framework for Perfectly Premixed Swirling Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a two-step optimization (TSO) framework, which uses the pressure data of an unstable combustion process to estimate the complex-valued flame transfer function (FTF). From the pressure time series, we obtain the ...
Image-Based Flashback Detection in a Hydrogen-Fired Gas Turbine Using a Convolutional Autoencoder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flame flashback (FB) is a major concern in hydrogen-fired gas turbines. In order to determine the flashback propensity of a hydrogen burner, several burner design tests at different operating points and fuel blends are ...
Hybrid Surrogate Modeling Approach for Data Reduction and Design Space Exploration of Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conventional iterative optimization of turbine blades using computer-aided engineering simulations is resource-intensive, with high costs and time demands, as well as significant challenges in computational requirements ...
Evaluation of Data-Driven Classifiers for an Ignition Forecast of Large Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Prediction of successful ignition is a challenging task that requires knowledge of the local thermochemical state in highly turbulent flow conditions. For typical industrial gas turbine (GTs) conditions operated on active ...
Quantification and Propagation of Uncertainties in Identification of Flame Impulse Response for Thermoacoustic Stability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermoacoustic behavior of a combustion system can be determined numerically via acoustic tools such as Helmholtz solvers or network models coupled with a model for the flame dynamic response. Within such a framework, ...
