摘要

讨论了多组分精馏塔定态模拟计算中三对角矩阵法的敛散性

并提出了一种修正法——二对角矩阵.对两种方法的收敛性进行了分析和比较

将这两种方法用于多种非理想体系的计算

结果表明

二对角矩阵法的收敛性和稳定性均比三对角矩阵法好.

Abstract

The convergence of the tridiagonal matrix method for multicomponent distillation is discussed with the principle of numerical analysis. A modified method

bidiagonal matrix method

is put forward. The two methods are compared in their convergence and stability. The application of the tridiagonal and bidiagonal matrix methods to the calculations of many non-ideal multicomponent distillations demonstrates that the latter is more stable than the former.
