This numerical study has focused on assessing the influence of adding 20% and 40%
hydrogen (on the volume of fuel basis) in different slots of a turbulent methane-air flame. The …

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) …

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 …

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 …

The present paper experimentally provides a quantitative comparison between the
aerodynamic flow field at non-reaction conditions (cold flow) and the combustion and …

Flame structures and thermoacoustic instabilities of centrally-staged swirl flames fueled with
methane at atmospheric pressure are experimentally investigated by varying the …

Temperature and radical concentration are the two most important factors affecting NOx
emissions in the methane combustion, while chemiluminescence is from the radiative …

Addressing burning characteristics of syngas under oxy-combustion conditions in
substantially CO 2-diluted combustion environment for gas turbine combustion applications …

In this study, artificial neural network (ANN) based on operating data is adjusted to detect
fault operation of large-scale industrial gas turbine. To detect faults, the operating …
