using chemiluminescence imaging of the excited
hydroxyl radical (OH*) and laser Raman scattering. The
DLR dual swirl burner is shown in Figure 16.11; several
experiments at atmospheric and higher pressure have
been conducted in this burner using methane-air ames
at conditions relevant to gas turbine engines. In this study,
the oxygen concentration was varied from 20% to 40% for
equivalence ...
