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

该奖项将支持俄亥俄州立大学NSF净形状制造工程研究中心在Taylan Altan博士的指导下与巴黎索菲亚-安提波利斯矿业学院的材料中心(CMFM)在Jean-Loup Chenot博士的指导下进行的压铸合作研究。这项研究将集中于开发数学技术和计算机程序，以模拟压铸过程中的金属流动和凝固。该计算机程序将能够预测凝固模式、显微组织和铸造性能。通过使用该程序，通过改变金属流动(射速)、模具和熔体温度等工艺条件，可以预测和避免潜在铸造缺陷的发生。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热传递的基本原理。CMFM在注塑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模拟。拟开发的研究和相关软件可能会在工业实践中有重要的应用。

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.
