Abstract : The performance of ramjets burning slurry fuels (leading to condensed oxide aerosols and liquid film deposits), gas turbine engines in dusty or marine atmospheres, or when using fuels from non-traditional sources, depends upon the formation and transport of small particles across non-isothermal combustion gas boundary layers (BLs). Even airbreathing engines burning "clean" hydrocarbon fuels can experience soot formation/deposition problems (e.g., combustor liner burnout, accelerated turbine blade erosion and "hot" corrosion). Moreover, particle formation and transport are important in many chemical reactors used to synthesize or process aerospace materials (turbine blade coatings, optical waveguides, ceramic precursor powders, fibers for composites,...) Accordingly, our research is directed toward providing chemical propulsion systems engineers and materials- oriented engineers with new techniques and quantitative information on important particle- and vapor-mass transport mechanisms and rates. The purpose of this report is to summarize our research methods and accomplishments under AFOSR Grant 91-0170 (Technical Monitor: J.M. Tishkoff) during the 3-year period: 15 February 91-14 February 94.
