In the present study, a series of experiments on the fuel jet from a 3D-printed swirling nozzle were performed. The particle size distribution of the fuel at different injection pressures was measured by a particle size analyzer, and the enhancement of the jet atomization by swirling air was also evaluated. The Rosin-Rammler distribution model was used to analyze the trend of the jet distribution modulus along with the fuel inject pressure, and the particle size variation analyzed the jet development process. The applicability of 3D printed nozzles for aero-engine was evaluated by varying the nozzle flow number.
