The centrally staged combustor is an effective way to reduce NOx emissions from
combustors. However, combustion instability caused by the mutual coupling between flames …

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 …

The high-temperature zone of a laboratory staged swirl gas turbine combustor was studied
under different Stratification Ratios (SR) based on experimentally validated Large Eddy …

Modern low-emissions gas turbine combustors commonly employ a twin annular swirling
flow configuration that consists of a central annular inner jet and a surrounding annular outer …

The present study investigates the effect of the exit geometry of the main stage on
thermoacoustic instabilities in a model combustor with a dual-swirl layout. In practical …

In this paper, the effects of pilot-stage equivalence ratio on combustion instabilities in a
coaxial staged model combustor are investigated using the Wall-Modeled Large Eddy …

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 …

Abstract Effects of heat loss on the thermoacoustic instability simulation were studied based
on flamelet-generated manifold (FGM) and large-eddy simulation (LES). The non-adiabatic …

Centrally staged lean premixed pre-vaporized (LPP) combustors are widely applied in
aeroengines to reduce pollutant emissions. However, combustion instability represents a …

In this study, three-dimensional flow structures at a Reynolds number of 16 000 are
measured by stereoscopic particle image velocimetry to reveal the dynamic structures of a …
