Particle image velocimetry (PIV) has become the chief experimental technique for velocity
field measurements in fluid flows. The technique yields quantitative visualizations of the …

One of the important choices for achieving decarbonization goals on a large scale is the
extensive use of H 2. However, the highly reactive nature of H 2 often leads to challenges …

This study investigates H 2-air flames obtained with a laboratory scale coaxial dual-swirl
injector in which fuel and oxidizer are injected separately. Two flame archetypes are …

The crux of the technical issues facing the development of hydrogen gas turbine engines is
the problem of how to enable low NOx, low dynamics combustor operations without …

The tremendous increase in energy demand due to increased population and rapid
economics results in an increased level of atmospheric pollutants and global warming. The …

Lean-premixed fuel-flexible combustion technology capable of operating on a wide range of
fuels, including high or pure hydrogen, is expected to play a crucial role in reducing nitrogen …

Methane and hydrogen-enriched (25 vol% and 50 vol% H 2-enriched CH 4) methane/air
premixed flames were investigated in a gas turbine model combustor under atmospheric …

Key issues facing the development of hydrogen gas turbines include achieving low NOx
emissions on hydrogen-enriched fuels, prevention of flashback and thermoacoustic …

Flame shapes and their transitions of premixed hydrogen enriched methane flames in a 3D-
printed low-swirl burner are studied using simultaneous OH× CH 2 O planar laser induced …

Operating lean-premixed gas turbine burners with fuels containing large amounts of
hydrogen severely increases the risk of flame flashback. Enabling fuel-flexible burners, ie …
