立并冻结壁温度场是一个相变温度场。它有移动内热源和比较复杂的迅值条件。目前尚无法作严格的理论解析。本文试图利用有限元法处理复杂的迅值条件及相变现彖。首先根据相似理论分析有限元法的计算结果,从而导出冻结壁温度场的准则方程及主要参数计算公式。最后,又用实例验证这些公式的正确性。文中对多孔交错的互相影响也做了初步考察。
Vertical and frozen wall temperature field is a phase transition temperature field. It has moving heat source and more complex fast conditions. At present there is no rigorous theoretical analysis. This article attempts to use the finite element method to deal with the complex conditions of rapid change and phase transformation. First of all, based on the similarity theory, the calculation results of the finite element method are analyzed, and the governing equations of the frozen wall temperature field and the calculation formulas of the main parameters are deduced. Finally, we verify the correctness of these formulas with examples. The paper also made a preliminary study of the mutual influence of porous interlacing.
