Aumento de la velocidad de convergencia del sistema de Rachford-Rice

The Regula-Falsi method to solve the equation f (x) = 0 is very adecuate when in the two first iterates x0 and x1, f (x) have opposite signs. Howewer, in some cases, the convergence of this method can be very slow, specially when i) the images through f of the extreme points of the search interval d...

description The Regula-Falsi method to solve the equation f (x) = 0 is very adecuate when in the two first iterates x0 and x1, f (x) have opposite signs. Howewer, in some cases, the convergence of this method can be very slow, specially when i) the images through f of the extreme points of the search interval differ, at least, in one order of magnitude; ii) in the zone where f (x) is smaller, f (x) ≈ 0 and iii) the root of f (x) is approximately in the mean of the search interval. For this cases, in this paper we propose a convergence accelerator function, wich is then used to calculate a adiabatic flash, where are present the characterisitcs of f mentioned above.
