摘 要:     通过双级雾化过程分析,建立了雾滴经历两次破碎的飞行和冷却数学模型,并进行了模拟计算;利用模拟计算结果分析了雾化工艺参数,并通过实验进行了初步的验证。结果表明:该模型基本能预测双级雾化雾滴的飞行和冷却过程,可为双级雾化工艺参数的选择提供理论依据。

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.
