The model is coupled with the droplets' heat transfer controlling equation and the droplets' motion controlling equation, and used in Cu-13.5%Sn (mass fraction) alloy. The effects of the droplet size, the initial gas velocity, the superheat of the melt and the wetting angle between the primary phase and the catalyzing substrate for heterogeneous nucleation on droplet solidification behaviors were discussed.
