Computation of gas phase equilibria—a general algorithm using the Newton-Raphson methodA general algorithm is proposed that calculates complex gaseous equilibria using the Newton-Raphson method. The algorithm was tested on the C-H-O-S-N system and its sub-systems H-O, C-H-O, C-O-S, C-...
上述方法都是全局收敛的,但如果在区间内有多个解,那么我们就需要更小的区间分别来寻找这些解。接下来会描述Newton-Raphson和割线法来求解,这两种方法都是求局部收敛的。这种局部收敛会收敛得更快。有部分算法会结合这两种类型的算法,在开始使用全局收敛,当接近根的时候再使用局部收敛。
