Project Number: 025
Category: Alternative Fuels
This work aims to accelerate the sustainable aviation fuel (SAF) design and approval process through development of a low-volume, prescreening approach based on detailed Fourier Transform Infrared (FTIR) spectral analysis. FTIR-measured gas-phase spectra and machine learning algorithms are used to develop new, robust ways to predict the physical, chemical, and combustion properties of SAFs and synthetic jet fuel components.
Past work focused on developing an extensive fundamental combustion database used to characterize and develop detailed kinetics models for jet fuels. Experiments were conducted to reveal how sensitive combustion properties are to variations in test fuel composition – variations that may help simplify the alternative fuel certification process.
This research is part of the National Jet Fuels Combustion Program.
