摘要
通过接触边界的偶联．导出了求解二维非连续域非稳态凝固传热问题的边界元法数学模型、编制了计算程序．以金属模型内的铸坯凝固传热为例进行了计算．计算结果与使用有限差分法的计算结果吻合．
This work established the formulation of two demensional unsteady heat tranfer of solidification with in homogeneous bodies by BEM. according to the coupling of interface between casting and meuld. The computational program is compiled. The casting solidification heat transfer problem is calculated as an example. The caculated results are similar with the calculated results by FDM.
