摘　　要：通过对喷射成形过程的分析,建立了喷射成形过程中金属液滴运动和传热的数学模型.利用该模型计算了喷射成形过程中雾化气体的速度、液滴速度、液滴温度、液滴的固相率等过程参量的变化过程.The mathematical model of droplet movement and its heat transfer were established through the analysis of spray forming process. The various process parameters such as velocity of gas, velocity of droplets, temperature of droplets and solid fraction of droplets were calculated by using the above-mentioned model.

关 键 词：喷射成形 金属液滴 传热 固相率
