To study the atomization performance of the centrifugal nozzle in the initial atomization stage, a traditional phase Doppler particle analyzer (PDPA) and a digital off-axis holography (DOH) were used. Using aviation kerosene RP-3 as the working fluid and maintaining the fuel pressure at 0.8 MPa, the atomization performance of the centrifugal nozzle at different fuel temperatures (240—300 K) was studied. The experimental results showed that: the spatial distribution of the Sauter mean diameter (SMD) in the initial atomization stage presented a “single peak” distribution, and with the increase of the axial distance, the peak value of the SMD increased, and the peak position of the SMD moved to the outside; for the same axial position of the initial atomization stage, because the change of fuel temperature could affect the length of the liquid film and the process of droplets breaking, the fuel temperature had no obvious regularity to the SMD distribution; the algorithm of droplets identification could identify the overlapping droplets as liquid filaments or irregular droplets. And the algorithm might exclude overlapping droplets from the statistical range, so the SMD and the peak position of the differential distribution of droplets size and number measured by DOH was smaller than that of DOH; DOH can directly observe the breaking process of the liquid film and the distribution of droplets, helping to analyze the experimental results.
