RISIgnition Probability and Lean Ignition Behavior of a Swirled Premixed Bluff Body Stabilized Annular Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation was performed in a premixed annular combustor equipped with multiple swirl, bluff body burners to assess the ignition probability and to provide insights into the mechanisms of failure and of ...
Soot Emission Simulations of a Single Sector Model Combustor Using Incompletely Stirred Reactor Network Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The simulation of soot evolution is a problem of relevance for the development of low-emission aero-engine combustors. Apart from detailed CFD approaches, it is important to also develop models with modest computational ...
Low-Order Modeling of Combustion Noise in an Aero-Engine: The Effect of Entropy Dispersion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work studies the effect of entropy dispersion on the level of combustion noise at the turbine outlet of the Rolls-Royce ANTLE aero-engine. A new model for the decay of entropy waves, based on modeling dispersion ...
Investigation of Flame Structure and Soot Formation in a Single Sector Model Combustor Using Experiments and Numerical Simulations Based on the Large Eddy Simulation/Conditional Moment Closure Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, a single sector lean burn model combustor operating in pilot only mode has been investigated using both experiments and computations with the main objective of analyzing the flame structure and soot formation ...
Estimation of Autoignition Propensity in Aeroderivative Gas Turbine Premixers Using Incompletely Stirred Reactor Network Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study of autoignition propensity in premixers for gas turbines is critical for their safe operation and design. Although premixers can be analyzed using reacting computational fluid dynamics (CFD) coupled with detailed ...
Quantification of Autoignition Risk in Aeroderivative Gas Turbine Premixers Using Incompletely Stirred Reactor and Surrogate Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design and operation of premixers for gas turbines must deal with the possibility of relatively rare events causing dangerous autoignition (AI). Rare AI events may occur in the presence of fluctuations of operational ...
