基于MeshTV界面重构算法的二元合金自由枝晶生长元胞自动机模型
Cellular automaton model with MeshTV interface reconstruction technique for alloy dendrite growth
摘要
Abstract
In this paper, cellular automata (CA) model for free dendritic growth of alloy is presented, in which the interface cell is refined by MeshTV interface reconstruction algorithm. In the present CA model, the growth kinetic for both pure material and alloy is used. The effect of interfacial energy anisotropy parameter e is validated in the CA model. The dendrite tip growth velocity and tip radius are compared with those of the LGK theoretical model, when e = 0.02.关键词
