Spray Segmentation

Institute of Combustion Technology for Aerospace Engineering

ML-models that can precisely segment sprays from shadowgraphy images.

Under gas turbine conditions, aerodynamic forces strongly influence the atomization performance of liquid fuels. Our research aims to enhance the fundamental understanding of these complex interactions through advanced quantitative diagnostics and data analysis. By developing state-of-the-art AI-based detection models, we analyse experimental data to accurately identify ligaments and droplets, thereby clearly describing the spray processes from primary atomization through turbulent dispersion. This comprehensive approach provides crucial insights that guide the optimization of injection systems, ensuring excellent atomization quality. Improved atomization enables rapid evaporation and optimal mixture formation, essential for reducing non-CO2 emissions such as nitrogen oxides (NOX) and particulates in advanced combustion systems.

Our ML-models

The developed model accurately resolves the gas–liquid interface contours within technical sprays, enabling detailed quantitative characterization of the atomization process from liquid jets, sheets, or films into ligaments and droplets. Validation using independent diagnostic techniques ensures high accuracy, robustness, and reliable predictions across diverse operating conditions.
