U.S.-France Cooperative Research: Simulation of Fluid Flow and Solidification in Die Casting

该奖项将支持美国国家科学基金会位于俄亥俄州立大学的净形制造工程研究中心（由Taylan Altan博士指导）和位于索菲亚-安提波利斯的巴黎矿业学院（Ecole de Mines de Paris, Sophia-Antipolis）由Jean-Loup Chenot博士领导的材料成型研究中心（CMFM）在压铸领域的合作研究。研究将集中在数学技术的发展和计算机程序模拟金属流动和凝固在压铸。计算机程序将能够预测凝固模式、显微组织和铸件性能。通过使用该程序，通过改变金属流动（射丸速度）、模具和熔体温度等工艺条件，可以预测和避免潜在铸件缺陷的发生。每个合作实验室都提供独特的分析和计算机建模能力。在这两个地方，研究人员都在研究流体流动和传热的基本原理。CMFM在注塑成型和铸造等过程的数学建模方面拥有丰富的经验。俄亥俄州立大学ERC拥有广泛的实验和计算能力，最近开始了铸造和凝固的计算机建模。所提出的研究和所开发的相关软件可能在工业实践中具有重要的应用。

This award will support collaborative research in die casting between the NSF's Engineering Research Center for Net Shape Manufacturing at Ohio State University, under the direction of Dr. Taylan Altan, and the Centre de Mise en Forme des Materiaux (CMFM), Ecole de Mines de Paris, Sophia-Antipolis, under the director of Dr. Jean-Loup Chenot. The research will focus on the development of mathematical techniques and a computer program for the simulation of metal flow and solidification in die casting. The computer program will be able to predict the solidification pattern, microstructures and casting properties. Through use of this program, occurrence of potential casting defects will be predicted and avoided, by modifying the process conditions such as metal flow (shot speed), die and melt temperatures. Each of the cooperating laboratories offers unique analysis and computer modeling capabilities. In both locations, researchers are working on the fundamentals of fluid flow and heat transfer. CMFM has extensive experience in the mathematical modeling of processes that involve such as injection molding and casting. The Ohio State University ERC has extensive experimental and computational capabilities and has recently started the computer modeling of casting and solidification. The proposed research and associated software to be developed may have important applications in industrial practice.
