Abstract : This project addressed variations in the chemical reaction rate as high-intensity turbulence interacts with premixed combustion fronts. Specifically, we aimed to experimentally quantify local reaction rate, and relate this to the local thermo-chemical structure.These objectives were achieved by simultaneous application of various high-speed laser-based measurement techniques in a series of piloted premixed jet ames, which were capable of achieving high Karlovitz numbers and low Damkohler numbers in a tractable and repeatable manner. Several advancements also were made in the areas of laser diagnostics and data-mining techniques.
