Bridgman法铸铁定向凝固一维传热分析

Heat Transfer Analysis of The Bridgman Configuration for Unidirectional Solidification of Cast Iron

基于铸铁定向凝固实验，将Ｂｒｉｄｇｍａｎ法定向凝固装置简化为由加热区和冷却区组成的二段式结构，推导出一个简明的一维传热解析解。通过理论分析与计算说明了该解使用的条件。

Considering practical conditions of unidirectional solidification experiments of cast iron, the Bridgman configuration is simplified as a structure consisting of hot zone and cold zone, and a simple analytical approch describing the heat transfer in the test sample has been developed . The conditions for which the approach is applicable have been expounded by theoretical analysis and calculations.
