Development and evaluation of gappy-POD as a data reconstruction technique for noisy PIV measurements in gas turbine combustors (2016, background): “For instance, lean premixed combustors are susceptible to thermoacoustic instabilities, which can decrease efficiency, increase emissions, and eventually lead to structural damage (Huang and Yang, 2009; Syred, 2006).”
Phase-resolved characterization of vortex–flame interaction in a turbulent swirl flame (2011, neutral): “6.3 Determination of 3D structure Previous studies have shown that the PVC is a 3D helical vortex structure that precesses around the central axis (Syred 2006).”
Large-eddy simulations of gas-turbine swirl injector flow dynamics (2007, background): “Such a precessing vortex core is often present when vortex breakdown occurs in a high-Reynolds-number flow, such as turbulent swirling flows in cyclone chambers and combustion devices (Gupta, Lilley & Syred 1984; Lucca-Negro & O’Doherty 2001; Syred 2006).”
Flow–flame interactions causing acoustically coupled heat release fluctuations in a thermo-acoustically unstable gas turbine model combustor (2010, background): “increases linearly with the bulk flow rate [13].”
Large Eddy Simulations of gaseous flames in gas turbine combustion chambers (2012, background): “Jet/IRZ interaction is often present and impacts the evolution of the PVC and even the IRZ itself asdiscussedby [228] (cf.”
Coherent structures in a swirl injector at Re = 4800 by nonlinear simulations and linear global modes (2016, background): “Axisymmetric breakdown is the cause of flow separation inside a nozzle in swirl injectors (Leibovich 1978; Syred 2006).”
