Project Number: 029
Category: Alternative Fuels
This project will develop models to predict the physical characteristics and behaviors of alternative jet fuels within jet engines. Of specific interest is the characterization of primary and secondary breakup of the liquid fuel into droplets and the subsequent evaporation.
