NUMERICAL STATISTICAL MODEL OF PRIMARY DENDRITIC SPACING
一次枝晶间距的数值统计模型

In view of the statistical randomness and the dynamic necessity, analysis has been conducted on morphology development of solid-liquid interface in directional solidification. Based on the present experimental observations and the known dendritic models, a numerical statistical model of primary dendritic spacing is first presented to the dendritic array in directional solidification at constant velocity. The numerical model is in good agreement with the experimental results.
