Boundary Layer Flashback Limits of Hydrogen-Methane-Air Flames in a Generic Swirl Burner at Gas Turbine-Relevant Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Operating stationary gas turbines on hydrogen-rich fuels offers a pathway to significantly reduce greenhouse gas emissions in the power generation sector. A key challenge in the design of lean-premixed burners, which are ...
Accurate Prediction of Confined Turbulent Boundary Layer Flashback Through a Critically Strained Flame Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel boundary layer flashback model is developed based on previous measurements that showed flashback limits may be related to strained premixed flame extinction. According to the model, flashback occurs at the equivalence ...
