Award for Creativity in Engineering

提出的研究探讨了与液态金属凝固有关的热、物质和流体动力学输运。这些耦合过程发生在凝固过程中的液体熔体中，并改变固体-浆液-液体界面的热量和物质传输速率，导致凝固速率的变化，最终导致成品机械和电气性能的变化。本建议的总体目标是通过主要的实验方法来增加我们对与液态金属凝固有关的传热和传质过程的理解。本研究最具创造性的特点是利用中子射线照相技术来可视化和测量纯金属或金属合金凝固过程中熔融金属中各种与传输相关的过程。

The proposed research investigates thermal, species, and hydrodynamic transport relevant to solidification of liquid metals. These coupled processes occur within the liquid melt during solidification and modify heat and species transport rates at the solid-mushy-liquid interfaces, inducing changes in the solidification rate and, ultimately, variations in the mechanical and electrical properties of the finished product. %%% The overall objective of this proposal is to increase our understanding of heat and mass transfer processes relevant to solidification of liquid metals with a primarily experimental approach. The most creative feature of this research is the utilization of neutron radiography to visualize and measure various transport-related processes within the molten metal during solidification of pure metals or metallic alloys.
