    Abstract

  • Aimed at the flow property in the start-up process of fuel slinger, three-dimensional numerical simulation was used to study the flow property of the inner and outer two-phase flow field of fuel slinger. Combined with the experimental results of high-speed photography and theory, comprehensive analysis was carried out. The results show that the total out mass-flow rate varies with time largely. Each hole's out mass-flow rate is also different to a great extent within short time period. The Sauter mean diameter (SMD) difference for different holes is relatively small compared with the SMD difference caused by rotation rate. The SMD is mainly determined by rotary speed. The spatial distribution of the spray is uneven as the result of different single holes' out mass-flow rate. The experimental results confirm the simulation outcomes.
