ABSTRACT CTS-9630801 Amon This work is a fundamental investigation of heat transfer and flow phenomena in microcasting. The spreading and solidification of molten metal droplets impinging on a surface will be modeled numerically and tested experimentally. Remelting of the solid substrate by the impacting droplet, modeling of dissimilar materials with potential simultaneous melting fronts, and modeling the continuous droplet/substrate system conjugately will be addressed. Spectral element direct numerical simulations of the governing thermo-fluid equations will be verified by experiments. Applications of this technology include manufacturing of multi-layer materials, artifacts with controlled microstructures, and artifacts with embedded electronic components.

摘要CTS-9630801 Amon 本工作是对微铸造中传热和流动现象的基础性研究。 熔融金属液滴撞击在表面上的扩散和凝固将被数值模拟和实验测试。 重熔的固体基板的影响液滴，建模的不同材料与潜在的同时熔化的前线，和建模的连续液滴/基板系统共轭将得到解决。 谱元直接数值模拟的控制热流体方程将通过实验进行验证。该技术的应用包括制造多层材料、具有受控微结构的工件以及具有嵌入式电子元件的工件。
