| 摘 要： | 燃烧过程和高温气体热力过程的计算需要求解燃气的化学平衡成分。本文提出了一种求解C_(n)H_(m)O_(l)N_(h)-空气系统化学平衡成分的双变量迭代法。与普通的简单迭代法相比,双变量迭代法的收敛性十分可靠;与赫夫法和怀特法相比,双变量迭代法的计算机程序十分简单、计算量极小(所需机时仅为前两者的10％～30％),而收敛性还有所改善。此外,对于贫油混气,文中还提出了双变量同时迭代的计算方案,使计算过程的收敛速度进一步提高。

| Abstract: | It is necessary to determine chemical equilibrium compositions for the calculation of combustion and thermodynamic processes of high temperature gases in various devices. A two-variable iteration method for the determination of chemical equilibrium composition of CnHmO1Kk-air system has been proposed in the present paper, which is characterized by good convergence, great convergence rate and simplicity of computer program. The amount of computation per iteration for the two-variable method is only about one tenth to one third of that for Huff method or Whith method. |
