Fluid Dynamics and Stability of the Planar-Flow Melt-Spin- ning Process

我们将进行实验和理论分析，以研究平面流动熔体旋压过程的流体力学和稳定性，这一技术有望在金属熔体的快速凝固中得到广泛的商业应用。将获得实际感兴趣的范围内的稳态流动及其对工艺操作参数的依赖关系的数据；这将使宏观带状几何形状的准确预测成为可能。稳定流动的稳定性将针对流场和弯月面的扰动进行测试；这将使带材表面质量的预测和控制成为可能。实验将检验理论的预测，并指导分析。

Experiments and theoretical analysis will be carried out to study the fluid mechanics and stability of the planar-flow melt-spinning process, a technique with promise for widespread commercial use in the rapid solidification of molten metals. Data will be obtained steady-state flows and their dependence on process operating parameters for ranges of practical interest; this will enable accurate prediction of macroscopic ribbon geometry. The stability of the steady flows will be tested against disturbances in flow-field and meniscus; this will enable prediction and control of ribbon surface-quality. Experiments will test predictions of the theory and guide the analyses.
