ABSTRACT
A turbulent reacting flow model has been developed, based upon a stochastic modeling approach that is applicable over a wide range of Reynolds and Schmidt numbers. All relevant length scales are resolved in one dimension which allows for direct implementation of detailed chemical kinetic calculations and molecular transport. Experiments were performed in a turbulent plug flow reactor for validation and application of the model to investigate the combined effects of turbulent mixing and chlorine chemistry on the formation of products of incomplete combustion. Methyl chloride was injected into the plug flow reactor whose baseline flow was the hot-product stream of a Toroidal Jet-Stirred Combustor. The micromixing and chemical reaction of the injected material with the baseline flow was monitored as a function of distance from the point of injection. Measurements of pulsed laser Rayleigh scattering were used to determine the extent of mixing while species concentrations were measured via extractive sampling and GC/MS. Preliminary comparisons of model calculations and data are provided which indicate the usefulness of the current modeling approach and provide insight into the relative contributions of mixing and chemical kinetics on the formation of products of incomplete combustion.
