| In order to obtain the relationship between the atomization performance and the geometry parameters of the triple swirler
combustor atomizer，the influence of the fuel supply pressure and the key geometry parameters such as length-width ratio and angle of swirl
port on fuel flow rate，spray cone angle and the atomization performance were studied experimentally. A three-dimensional Phase Doppler
Particle Analyzer（PDPA）was used to measure the Sauter Mean Diameter（SMD）and number density distribution of points on a line and the
characteristic diameter and uniformity index of the Rosin-Rammler distribution. The results show that the fuel flow rate and spray cone
angle increase when the fuel supply pressure increases. The change of swirl port geometry parameters has different influence on fuel flow
rate and spray cone angle. When the swirl port length-width ratio and swirl port angle increase，the fuel flow rate decreases and the spray
cone angle increases. The law obtained by the study provides an important theoretical basis for the atomizer optimization design of the triple
swirler combustor. |
