Data underlying above publication and other Deliverables of LEAFINNOX project. This database contains raw and processed data from the experimental activities undertaken at the University of Cambridge under the EU Clean Sky 2 project LEAFINNOX. In this project, Cambridge developed a new burner for hydrogen and liquid fuels, including Sustainable Aviation Fuels, that has the potential to be further developed for use in an aviation gas turbine. The dataset contains images (from chemiluminesence-monitoring camera), operating conditions (flow rates, pressures etc), emissions (species concentrations and soot composition) and other data that support the publications and further modelling or experimental studies
