摘要
对比不同函数近似形式在过冷壁面与不同熔融物过热度下与精确解析解间的误差,选取适合计算过冷壁面上过热熔融物凝固问题的函数近似形式。结合准稳态方法研究3层结构下熔融物凝固过程中凝固层厚度随时间的变化。计算结果与数值计算结果、平衡态计算结果以及实验结果符合较好,证明采用准稳态热平衡积分方法求解3层有限结构的过热熔融物凝固问题是可行的。
Relative errors between results from different HBI methods under different conditions and analytical solution are compared and analyzed in this paper. Quadratic approximation is chosen for the calculations of freezing process of overheat melt on cold structure by comparison results of relative errors. HBI under quasi-steady state is applied in this paper and results suit well with numerical results.
