定向凝固过程可分为两个阶段即为抽拉前的稳态过程和抽拉后的非稳态过程,此部分用边界元法对三维瞬态过程进行了数值模拟,给出了定向过程中的热源及温度分布特性。
Directional solidification process can be divided into two stages: the steady-state process before drawing and the unsteady process after drawing. In this part, the three-dimensional transient process is numerically simulated by the boundary element method, and the orientation process Heat source and temperature distribution characteristics.
