Aluminum Droplet Combustion:Rates and Mechanisms in Wet and Dry Oxidizers.

摘要

The report describes quantitative single aluminum droplet combustion studies in a variety of gaseous oxidizers including CO2and water vapor. A laser ignition technique was employed which has a demonstrated ability to yield metal droplet burning data of very low scatter. A discussion of droplet burning models is included and the faulty assumptions underpinning them are identified. Based on experimental findings,an outline is given of the direction modeling must take to accurately describe Al droplet combustion. (Modified author abstract)
