本文的目的是探索二元合金凝固的可能的单相模型的范围。从一般的两相描述出发，基于双流体模型，确定了三种极限情况，从而得到二元体系的单相模型。这些模型中的每一个都可以容易地在标准单相流数值代码中实现。从这些模型的预测之间的差异进行检查。特别是，预测的宏观偏析模式的模型的影响进行了评估。
The aim of this paper is to explore the range of possible one-phase models of binary alloy solidification. Starting from a general two-phase description, based on the two-fluid model, three limiting cases are identified which result in one-phase models of binary systems. Each of these models can be readily implemented in standard single phase flow numerical codes. Differences between predictions from these models are examined. In particular, the effects of the models on the predicted macro-segregation patterns are evaluated.
