Abstract

The effect of heavy liquid fuel properties on the atomization characteristics is  introduced. Detailed measurements of the drop size and the velocity distribution  were obtained for a twin fluid externally mixing atomizer. The Phase Doppler  Particle Analyzer is used in the current measurements. The simultaneous  
measurement of drop size and velocity was the major importance in accurately  describing the changes in the local drop size distributions and mass flux. Result shows a noticeable decrease in droplet size distribution and the corresponding  droplets velocity with increasing fuel temperature. A mathematical model was  developed to predict the atomization process.
The stochastic separated flow model  (SSF) as well as modified interaction mechanism between the two phases of the spray were taken into account to improve the capabilities of the prediction method.
