The centrally staged combustor is an effective way to reduce pollutant emissions. However,
combustion instability is one of the prominent and unavoidable problems for lean premixed …

This study mainly investigates the flame and flow characteristics under combustion instability
in a centrally-staged swirl spray combustor, using 5 kHz CH* chemiluminescence (CL) and …

Abstract Knowledge of the underlying physical mechanisms responsible for the triggering of
high-frequency transverse combustion dynamics is of fundamental importance in the …

This paper presents an experimental study on the emergence of the central recirculation
zone (CRZ) in a basic V-shaped premixed swirling flame, using simultaneous measurement …

This work investigates the influences of precessing vortex cores (PVCs) on the coherent
interactions in the transient flow and heat release fields of a weak premixed swirling flame …

The main focus of this paper is to discover the link between flame macrostructure and
thermoacoustic instability in a centrally staged swirl burner. In practical combustors, the flow …

This paper reports two distinct vortex-flame interaction mechanisms existing in a self-excited
V-shaped premixed flame. Time-resolved simultaneous measurements of particle image …

The pilot stage plays a crucial role in central-staged combustion technology. This study
aimed to investigate the impact of the jet-type pilot stage on the flame structure and …

This paper examined the influence of adjacent nozzles on the flow and fuel atomization
characteristics of the central nozzle in a triple-nozzle model combustor. High-frequency …
