Optimal design of shell-and-tube heat exchangers using particle swarm optimization / Mauro A. S. S. Ravagnani in Industrial & engineering chemistry research, Vol. 48 N° 6 (Mars 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 2927–2935 Titre : Optimal design of shell-and-tube heat exchangers using particle swarm optimization Type de document : texte imprimé Auteurs : Mauro A. S. S. Ravagnani, Auteur ; Aline P. Silva, Auteur ; Evaristo C. Biscaia Jr., Auteur Année de publication : 2009 Article en page(s) : pp. 2927–2935 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Shell-and-tube  heat  exchangers  Particle  swarm  optimization  Bell−Delaware  method Résumé : In this paper, the shell-and-tube heat exchangers design is formulated as an optimization problem and solved with particle swarm optimization (PSO). The objective is to minimize the global cost including area cost and pumping cost or just area minimization, depending on data availability, rigorously following the standards of the Tubular Exchanger Manufacturers Association and respecting pressure drops and fouling limits. Given fluids temperatures, flow rates, physical properties (density, heat capacity, viscosity, and thermal conductivity), pressure drop and fouling limits, and area cost data, the proposed methodology calculates the optimal mechanical and thermal-hydraulic variables. The Bell−Delaware method is used for the shell-side calculations. Some literature cases are studied and results show that in this type of problem, with a very large number of nonlinear equations, the PSO algorithm presents better results, avoiding local minima.
