最近发现,在地球重力条件下,利用传统的气体雾化技术,可以在地球上制备不相容液态合金的核-壳和核-壳-晕微结构,这些微结构以前只能在外层空间获得。这完全归因于界面能随温度变化而驱动的Marangoni运动。借助于计算机模拟,我们发现,调幅分解、分解诱导的流体流动、第二相液滴之间的碰撞和碰撞诱导碰撞的耦合过程在这些结构形成的不同阶段都起着关键的作用。分析了它们相对于Marangoni效应的贡献作为系统大小的函数。
It was recently discovered that core-shell and core-shell-corona microstructures in immiscible liquid alloys, which were previously obtained only in outer space, can be fabricated under gravity condition on earth using conventional gas atomization. The origin was attributed solely to Marangoni motion driven by temperature-dependence of interfacial energy. We found in this letter, with the aid of computer simulation, that coupled processes of spinodal decomposition, decomposition-induced fluid flow, collision and collision-induced-collision among second-phase droplets all play critical rules at different stages in the formation of these structures. Their contributions relative to the Marangoni effect are analyzed as function of system size.
