摘要
本文提出构造流程模拟系统中非线性迭代算法的一种组合方法,并就基于 Broyden 类似牛顿算法的新的组合程序的构造进行了深入讨论。将这种组合程序用于 F-T 合成回路的收敛迭代,在数值稳定性和收敛速度上都较单一方法优越。
The paper introduces a combined method for creating nonlinear iteration algorithm in
process simulation systems and discusses the combined program based on Broyden-like
quasi-Newton algorithm.The program was used in iteration of Fischer-Tropsch synthesis
process loop and showed better numerical steadiility and higher speed than that of any sin-
gle algorithm included in the combined program.
