摘要
采用近似分析方法对熔融物完全排除的有限厚度的无限大板熔融问题进行了较为细致的探讨。针对具有恒热流边界的情况 ,得出了熔融位置随时间变化的无量纲关系式 ,并讨论了不同边界条件、初始条件及不同斯蒂芬数 (Ste)对熔融曲线的影响。
Melting of an infinite flat plate with specified thickness, heat flux boundary conditions, and complete removal of melt is analytically investigated. Dimensional and dimensionless expressions for the relation between melting time and melt line location are obtained by an approximate integral method. The curves based on the dimensionless expressions are plotted, and the influencing factors are discussed.
