This investigation will both experimental and numerical. The objectives of the proposed research are as follow: 1) Experimental Investigations (These are divided into two parts). a) Experimental investigation of double- diffusive convection in a static V-shaped sump during the binary system solidification process. b) Experimental investigation of double- diffusive convection during the continuous casting process. 2) As far as the numerical investigation is concerned, this section is also divided into two parts. a) Development of mathematical modeling and refinement. b) Numerical study of the continuous casting process. The specific objectives are to obtain velocity, temperature, concentration distribution, and the evaluation of the solid liquid interface in the cases cited for which rigorous experimental and numerically results are not available, and to present correlations, tables and graphs for use in industrial applications. It is believed that the availability of accurate experimental/numerical results for these fundamental problems is important from an academic and practical point of view and that they will further enhance research in these area.

本研究将采用实验和数值两种方法。 拟议研究的目标如下： 1)实验研究（分为 两部分）。 a）、 双金属复合材料的实验研究 静态V形扩散对流 二元系凝固过程中的贮槽 过程 B） 双金属复合材料的实验研究 持续期间的扩散对流 铸造工艺 2)就数值研究而言， 本节也分为两个部分。 a）、 数学建模与 精致。 B） 连铸过程的数值模拟研究 过程 具体目标是 获得速度、温度、浓度 分配和评价 固液界面 严格的实验和 数值结果不可用， 来呈现相关性，表格和图表 用于工业应用。 是 我相信，准确的 实验/数值结果 基本问题是重要的， 学术和实践的观点， 他们将进一步加强研究， 这些地区。
