摘要: 从动力学和传热学角度对Fe-66.7%Si(原子分数)合金液滴在充入不同种类和压力保护气体的落管中下落的运动过程和温度变化情况进行了计算分析. 从重力水平和熔体冷却速率等方面对该合金液滴落管凝固实验的保护气体种类和压力选择进行了讨论.

Abstract:The motion, microgravity level, and temperature of the Fe-66.7%Si (atomic fraction) droplets free falling in a drop tube filled with various inert gases under different pressures were computed. Based on the computation, the principle of choosing the proper inert gas and gas pressure was discussed in view of the gravity level and the melt cooling rate.
