In this work, we propose and test a partial premixed fuel injection design of NH 3− H 2− O 2
with double ring-shaped inlets to enhance ammonia combustion in an open-ended …

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 …

In this paper, deep learning is involved to comprehend thermoacoustic instability more
deeply and achieve early warning more reliably. Flame images and pressure series are …

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 …

MILD combustion technology is expected to enable safe and stable low-emission
combustion of hydrogen-doped fuels, or pure hydrogen fuels, in gas turbines designed for …

Suppressing thermoacoustic oscillations in low-emission combustors during their operation
poses a major challenge. In this study, we report dynamic flame tests on combustors with …

This study focuses on the center-staged swirl model combustion chamber, conducting
experiments and numerical simulations to investigate the unstable combustion …

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

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 study experimentally explored the effects of equivalence ratio settings on ethanol fuel
combustion oscillations with a laboratory-scale combustor. A contrary flame equivalence …
