利用由金属物理学的基本概念导出的含一级相变非线性热传导方程,在微时段内线性化,由变物性线性化泛函,建立了金属凝固过程中温度场的有限元方程并对轴对称问题的金属凝固过程中的温度场作了数值模拟和测试。得出比较满意的结果。
By using the first-order phase transition nonlinear heat conduction equation derived from the basic concept of metal physics and linearizing in a micro-time period, the finite element equation of the temperature field in the solidification process of the metal The temperature field in the process of metal solidification with symmetry is numerically simulated and tested. Come to more satisfactory results.
