The structure and dynamics of reacting two stream plane mixing layers

Studies have been conducted of premixed flows in which a flame is stabilized by the mixing of hot products with cold reactants in a mixing layer. The present paper has the objective to provide an outline of the experimental issues, and to summarize the experimental results which have been obtained. A description of the experimental apparatus is presented, taking into account the combustor facilities, aspects of flow visualization, the conduction of velocity measurements, and density measurements performed with the aid of a laser Rayleigh scattering technique. Attention is given to the experimental conditions and results, the steady behavior, the unsteady behavior, the modeling of the two stream mixing layer flow, and random vortex modeling.
