Control of Thermodiffusion in Liquid Multicomponent Alloys

目的：该项目旨在通过数学描述、实验测量和模拟计算，全面研究液态合金中的热质耦合。意义：当液态合金存在于不同的温度下时，热量和质量流的耦合会导致其成分的快速偏析。这是在制造中控制液态合金凝固和设计用于有效传热的液态合金冷却剂的主要复杂性。这一问题从未得到解决。 预期成果：这项研究有望成为该领域的开创性基础。好处：预计这项研究将提供适当控制液态合金工程使用的方法。

Aims: The project aims to comprehensively study heat and mass coupling in liquid alloys by describing it mathematically, measuring it experimentally and calculating it by simulation. Significance: When a liquid alloy exists at different temperatures, the coupling of heat and mass flows causes rapid segregation of its components. This is a major complication in controlling solidification from liquid alloys in manufacturing and in the design of liquid alloy coolants for efficient heat transfer. It has never been addressed. Expected outcomes: This research is expected to be the pioneering foundation of the area. Benefits: It is anticipated that the research would provide the means to properly control the engineering use of liquid alloys.
