| Abstract: |
| Based on structure of close-coupled nozzle, atomization process of high temperature melt was simulated with Fluent Soft to investigate influence of superheat on flight distance of atomized droplets before solidification and droplet breakup degree. The results show that it is beneficial to refine particle size of atomized particles when the average diameter (SMD) drops with rise of superheat. Flight distance of droplets before solidification is relatively flat with a slight rise in this progress. When superheat reaches 100 ℃, breakup of droplets is relatively sufficient, and the average diameter of particles meets production requirements. Average diameter of particles is 52.886 μm, and flight distance of droplets before solidification is 32.68 mm after atomization of melt. |
