Numerical simulation of non‐isothermal phase change problem using ADRBEM with augmented items

In this paper, the phase change moving interface problem along the axial direction of the cylinder in the lead alloys 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 a certain condition. The calculating results show that the ADRBEM with augmented items is an effective numerical method to solve the analogous problem of non‐isothermal phase change, which occurs in the crystal growth process. © 2007 Wiley Periodicals, Inc.
