| Abstract: | This paper verified with a certain engine nozzle as the prototype.Phase Doppler particle Analyzer/ laser Doppler velacity meter(PDPA/LDV) is used to investigate the pressure atomizering injector characters.These texts include oil-supplying performance,spray cone angle and atomization granularity.The combustor flame tube which installed in the injector was numerically simulated using Fluent software.The testing and calculation results given some valuable conclusions,which is proved benefit to understand the fuel injector,the temperature field and the velocity field of the flame tube well.These results given out important reference for the combustor and injector improvement. |
