Abstract : Computer models of turbulent mixing and combustion suffer from many limitations, deficiencies, and errors. To evaluate and refine them, an experimental research program was started (a) to develop a combustion test facility and optical diagnostics, (b) to perform turbulent mixing and combustion experiments, and (c) to provide a database for modeling needs. This final report describes the combustion test facility and the optical instrumentation, namely a Laser Doppler Anemometer (LDA), and a Laser Raman/Rayleigh Spectroscopy (LRS) system. The problem areas, error analysis, and data reproducibility of these optical techniques are discussed. Keywords: Turbulent combustion; Jet flows; Recirculatory combustion; Nonreacting flows; Bluff-body; Near wake. (jes)
