AbstractThis paper describes the development of a high-pressure spray test facility for performance evaluation of aero-engine fuel injectors. The facility provides test conditions of elevated inlet air-pressure up to 1 MPa. The maximal airflow rate is 1.2 kg/s at 0.8 MPa so that the facility is even capable of evaluating the performance of the next generation low emission burners based on lean premixed pre-vaporized combustion. The facility features a test section equipped with large high-pressure windows and an auxiliary air-purge system. The former gives optical access to various measurement techniques, and the latter keeps droplets away from the window surface and thus provides a clear view of sprays for a period sufficiently long for the measurements. The paper presents features and functions of the facility, together with some of the spray measurement techniques having been applied so far, along with examples of the measurement results. Suggestions for future work are also made, including those for further improvements of the facility.
