摘要 采用凝固的混合流模型对PbSn二元合金的凝固过程进行了数值研究,求解完全耦合的动量、能量和组分的输运方程,讨论了液相质量分数的求解方法,比较了不同的固相扩散模型对溶质宏观偏析的影响.数值计算结果和实验结果进行了比较分析,对模型改进做了进一步的探讨. A continuum model for simulating the solidification of Pb-Sn binary alloy is given. Different models for the diffusion in the solid are described and compared for their effects on solidification and macrosegregation. The complete coupling of momentum, energy and species equations are solved and some numerical aspects of solute liquid mass fraction are presented. The computational results are compared with the experiment. Future modifications about the model are discussed
