Home > GDTech Engineering > Calibration of an LES Code for Predicting Pollutant (NOx) Emissions in an Aeronautical Combustion Chamber

As part of the FICOSI R&T project (Industrial SME/SMI Sector for Combustion and Injection Systems), GDTech worked on understanding pollutant formation mechanisms, their numerical implementation in a CFD code, and evaluating a code to predict NOx levels. This work was carried out using engine test results from a Safran Helicopter Engines.
This R&T project is part of the future investment program.

• Literature Review on NOx Formation Mechanisms
• Evaluation of a simulation code’s ability to predict the temperature map at the chamber outlet and NOx emission indices
• Fuel droplet modeling (two-phase approach)
• Comparison of numerical results with test data (temperature map at the chamber outlet and EINOx)
• Identification of levers to reduce NOx production.
