Calculation of critical points of thermodynamic mixtures with differential evolution algorithms / Henderson, Nélio in Industrial & engineering chemistry research, Vol. 49 N° 4 (Fevrier 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 4 (Fevrier 2010) . - pp 1872–1882 Titre : Calculation of critical points of thermodynamic mixtures with differential evolution algorithms Type de document : texte imprimé Auteurs : Henderson, Nélio, Auteur ; Sacco, Wagner F., Auteur ; Barufatti, Nelza E., Auteur Année de publication : 2010 Article en page(s) : pp 1872–1882 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Thermodynamic  Differential  evolution  algorithms. Résumé : In this article, we use differential evolution (DE) algorithms for the first time in the prediction of critical points of thermodynamic mixtures. Despite the name, DE algorithms are direct search populational techniques that do not use derivatives. We work with four different versions of DE algorithms and propose a variant for calculating more than one critical point. The differential evolution algorithms are tested on several multicomponent systems, and the new variant is capable of obtaining multiple solutions on different petroleum fluids.
