| 摘 要： | 对铅-锡合金的相变问题,本文采用含扩展项的轴对称双倒易边界元方法计算了圆柱中界面沿轴向运动的非等温相变过程。与特定条件下解析解的比较,验证了该方法的正确性,为类似的晶体生长非等温相变问题提供了一种有效的求解方法。

| Abstract: | In this paper, the phase-change moving interface problem along the axial direction of the cylinder in the alloys of lead containing tin is simulated by the Axisymmetric Dual Reciprocity Boundary Element Method (ADRBEM) with augmented items. The numerical method is verified by comparing with the analytical solution under the certain condition. The results show that the ADRBEM with augmented items is an effective numerical method to solve analogous problem of non-isothermal phase change, which occurs in the crystal growth process. |
