![]() A large diffuse cloud of CH2O is formed downstream of the quenching point. The flame features a bowl-shape stabilization, with a corrugated, continuous flame front at the leading edge, followed by fragmented reaction zones downstream. The simulation and experimental results show excellent agreement. Karlovitz and turbulent Reynolds numbers are 300 and 400, respectively. The inflow is prescribed to match experimental measurements at the burner exit. The premixed fuel-air mixture more » consists of hydrogen-enriched methane with 70% hydrogen volume fraction and 0.4 equivalence ratio. The adaptive-mesh refinement solver PeleLMeX is used, with 24-species, 105-reaction reduced Aramco chemical kinetics mechanism. The results from the laboratory flame include simultaneous measurements of velocity using stereo particle imaging velocimetry and OHxCH2O planar laser induced fluorescence. We present results from a direct numerical simulation (DNS) of a turbulent CH4/H2 model GT low-swirl laboratory-scale flame interacting with an inclined wall. FWI has direct consequences on flame stabilization and pollutant emissions, but it is not well understood in turbulent flows representative of GTs. « lessĭue to downsizing trends, flame-wall interaction (FWI) is increasingly prominent in gas turbines (GTs). Such insight will be useful for scaling the LSI to operate at IGCC conditions. ![]() These results show that the LSI exhibits the same overall behaviors at STP and at gas turbine conditions. The objective of this study is to conduct laboratory experiments on low-swirl injectors (LSIs) to obtain the basic information for adapting LSI to burn H emissions show a log linear dependency on the adiabatic flame temperature and the concentrations are similar to those obtained previously in a LSI prototype developed for natural gas.
