| 摘 要： | 本文对模拟高温热交换场的段法数学模型的能量平衡方程组提出了主变量修正解法。利用方程组的主变量性将一组n元非线性方程的求解,分解为n个一元非线性方程的求解;而对于每个一元非线性方程,又采用简化直接法求解,减少一个迭代层次。本解法在任意初值下均可保证收敛。

| Abstract: | In this article,the Main Variable-Correction Method is presented to get the solution of energy equations which has been being,for a long time,one of main difficuties in Zone-method for heat exchange field in high temperature.By making use of the nature of main variables in equations, the solution of N-dimens-ional nonlinear equations can be resolved into that of N one-dimentional nonlinear equations each one of which can be solved with simplified direct method to simplify the iteration procedure.This method can be assured to get covcr-gence of the solution of equations at any initial values. |
