论文发展了一个能求解带相变运动界面非定常传热和非线性热物理特性问题的双倒易边界元方法。数值模拟了半透明单晶生长中热过程的一个例子。由于方法是纯边界积分方法，计算量与计算内存都大大减少。获得了单晶生长过程瞬态温度场分布和固液相界面形状时间推进的一些结果。
The dual reciprocity boundary element method (DRBEM) has been developed tosolve unsteady heat transfer problems with phase change moving interface andnon-linear thermophysical properties. An example of numerical simulation ofthe thermal process in semi-transparent crystal growth has been made. Sincethe method is pure boundary integral method, this provides a considerablereduction in the storage and the computational requirements while improvingaccuracy. Some results of transient temperature fields and time marchingsolid-liquid phase-change moving interface in the crystal growth are presentedin this paper.
