Ammonia (NH 3) has recently emerged as a promising carbon-free energy carrier. Further
development and application of NH 3 as fuel in the gas turbine industry can significantly …

Abstract Large Eddy Simulation (LES) is conducted for the combustion instabilities of the
stratified swirling flames. Two different pilot-stage equivalence ratios (Φ p), 0 (lifted flame) …

In this study, we developed a diagnosis method for combustion instability and validated its
performance using experimental data obtained from a hydrogen/natural gas co-firing gas …

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 …

Multi-bifurcation behaviors of staged swirl flames fueled with methane at atmospheric
pressure are experimentally investigated by varying the global equivalence ratio (⁠ ϕ glo⁠) …

Centrally staged swirl combustion can effectively reduce NO x emission. However, the
complex combustion field is susceptible to producing large-scale coherent structures, such …

In the start-up process of practical gas turbine applications, the modulation of operating
condition, especially the variation of global equivalence ratios (ϕ glo), could cause the …

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 …

Combustion instabilities have been a plaguing challenge in lean-conditioned propulsion
systems. An open-loop control system was developed using machine learning to suppress …
