Synopsis

Stabilization and Dynamic of Premixed Swirling Flames: Prevaporized, Stratified, Partially, and Fully Premixed Regimes focuses on swirling flames in various premixed modes (stratified, partially, fully, prevaporized) for the combustor, and development and design of current and future swirl-stabilized combustion systems. This includes predicting capabilities, modeling of turbulent combustion, liquid fuel modeling, and a complete overview of stabilization of these flames in aeroengines. The book also discusses the effects of the operating envelope on upstream fresh gases and the subsequent impact of flame speed, combustion, and mixing, the theoretical framework for flame stabilization, and fully lean premixed injector design.

Specific attention is paid to ground gas turbine applications, and a comprehensive review of stabilization mechanisms for premixed, partially-premixed, and stratified premixed flames. The last chapter covers the design of a fully premixed injector for future jet engine applications.

• Features a complete view of the challenges at the intersection of swirling flame combustors, their requirements, and the physics of fluids at work
• Addresses the challenges of turbulent combustion modeling with numerical simulations
• Includes the presentation of the very latest numerical results and analyses of flashback, lean blowout, and combustion instabilities
• Covers the design of a fully premixed injector for future jet engine applications

Stabilization and Dynamic of Premixed Swirling Flames

Prevaporized, Stratified, Partially, and Fully Premixed Regimes

Paul Palies

CFDRC, Huntsville, AL, USA

Stabilization and Dynamic of Premixed Swirling Flames focuses on swirling flames in various premixed modes (prevaporized, stratified, partially, and fully premixed) for the combustor and the development and design of current and future swirl-stabilized combustion systems. This includes predicting capabilities, modelling of turbulent combustion, , and a complete overview of the topic of stabilization and combustion dynamics of these flames in aeroengines. The book also discusses the effects of the operating envelope on upstream fresh gases and the subsequent impact on flame speed/combustion/mixing. It presents a theoretical framework for flame stabilization. The last chapter covers the design of a fully premixed injector for future jet engine applications.

Key Features

• Provides a comprehensive review of stabilization mechanisms for prevaporized, stratified, partially and fully premixed flames
