U.S.-Argentina Cooperative Research: Simulation of Defects in Castings

小行星9802518 这个美洲计划奖将资助大卫R博士之间的合作研究项目。Poirier和Juan C.亚利桑那大学的海因里希和S。Felicelli和E. Basombrio，Centro Atomico Bariloche，阿根廷，关于合金铸件凝固的建模和模拟。 研究的主要目标是生产无气孔的结构铸件，以避免形成通常导致定向凝固过程的缺陷。 研究人员的目标是开发适合研究铸造缺陷形成的复杂三维形状的模拟器。 这项合作将补充亚利桑那大学的两个项目，这两个项目模拟了孔隙的形成。 巴里洛切原子中心的研究人员凭借他们在移动界面数值建模方面的经验，将为这些程序添加一个重要的组成部分。 这两个小组还将共同继续完善孔成核的初步模型。 来自亚利桑那大学和巴里洛切原子中心的几名研究生将参与这项研究，无论是开发新模型及其计算机程序，还是将模拟器与实验工作结合起来使用。 ***

9802518 Poirier This Americas Program award will fund a cooperative research project between Drs. David R. Poirier and Juan C. Heinrich, of the University of Arizona, and Drs. S. Felicelli and E. Basombrio, Centro Atomico Bariloche, Argentina, on the modeling and simulation of solidification in alloy castings. The major objective in the research is to produce porosity- free structural castings in order to avoid the formation of defects which usually result in directional solidification processes. The researchers aim to develop simulators for complex three-dimensional shapes suitable for studying the formation of casting defects . This collaboration will complement two programs of the University of Arizona, which model the formation of porosity. The investigators at Centro Atomico Bariloche, with their experience in numerical modeling of the moving interfaces, will add an important component to these programs. Together, both groups will also continue to refine a preliminary model on pore nucleation. Several graduate students from both the University of Arizona and Centro Atomico Bariloche will be involved in the research, either in the development of new models and their computer programs, or in the use of the simulators in conjunction with experimental work. ***
