RISCorrespondence Between “Stable†Flame Macrostructure and Thermo acoustic Instability in Premixed Swirl Stabilized Turbulent Combustion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we conduct an experimental investigation to study the link between the flame macroscale structure—or flame brush spatial distribution—and thermoacoustic instabilities, in a premixed swirlstabilized dump ...
Impact of a Centerbody on the Unsteady Flow Dynamics of a Swirl Nozzle: Intermittency of Precessing Vortex Core Oscillations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The precessing vortex core (PVC) is a self-excited flow oscillation state occurring in swirl nozzles. This is caused by the presence of a marginally unstable hydrodynamic helical mode that induces precession of the vortex ...
