Abstract:A computer model has been developed to describe the dynamic and thermal behavior of droplets in fragmentation process based on the studies on two stage atomization process. According to the model, the dynamic and thermal behavior of Al-20Si alloy droplets were calculated, and the technological parameter of two-stage atomization was discussed. The calculated result was also verified by atomization testing.
Key words: atomization; computer; simulation; droplet
