Abstract
Combustion rate and stability are strongly related to the interaction of fluid dynamics with the combustion process in reactive flow systems. The ability to control the combustion depends on the understanding of this interaction. This paper describes the use of the Planar Laser Induced Fluorescence (PLIF) technique to get insight into these processes, by looking at the coherent and random structures of a combusting jet. The coherent structures educed by phase-locked averaging are significantly different from instantaneous pictures, which are highly three dimensional. The PLIF images clarify the relationship between the large-scale structures and the generation of small-scale turbulence.
