Abstract

This contribution describes a newly derived development chain for the early design and validation phases of lean burning injectors allowing a faster and cheaper design process. It comprises an initial concept definition, design optimizations based on CFD and a design validation by qualitative fuel flow tests, followed by the application of laser diagnostic methods. Finally, emission and operability characteristics are determined at real operating conditions. The comprehensiveness of the applied development chain has been proved to significantly reduce NOx emissions of the lean burners and to generate validated design rules for the fuel injectors analyzed in this study.
