The Digest’s 2025 Multi-Slide Guide to Fuel effects on aviation engine emissions – a modeling tool for SAF screening

This project delivers a low-computational-cost 0-D/1-D reactor network tool to rapidly screen Sustainable Aviation Fuels (SAF). The tool, validated against CFM56 engine data, incorporates reduced chemical kinetic mechanisms for fuel effects on emissions (NOx, CO, PM, PN). This technology enables fuel producers and OEMs to accelerate aviation decarbonization by de-risking new SAF candidates. The model confirms that NJFCP fuels reduce soot emissions without penalizing NOx or CO.
