A dimensionless description of active magnetic regenerators to compare their performance and to simplify their optimization / Giulio Tagliafico in International journal of refrigeration, Vol. 36 N° 3 (Mai 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 3 (Mai 2013) . - pp. 941–949 Titre : A dimensionless description of active magnetic regenerators to compare their performance and to simplify their optimization Titre original : Description adimensionnelle des régénérateurs magnétiques actifs permettant de comparer leur performance et de simplifier leur optimisation Type de document : texte imprimé Auteurs : Giulio Tagliafico, Auteur ; Federico Scarpa, Auteur ; Luca A. Tagliafico, Auteur Année de publication : 2013 Article en page(s) : pp. 941–949 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Magnetic  refrigerator;  Regenerator;  Magnetocaloric  effect;  Dimensionless;  Standardization Résumé : The behavior of active magnetic regenerators (AMR) can be described by means of a one-dimensional set of equations. A lot of geometrical, thermo-physical and magnetic parameters influence the behavior and performance of an AMR, together with external controls and operating parameters. Literature data on AMR performances, both experimental and numerical, are given in different conditions and configurations, so that a consistent comparison among different results is not straightforward, and sometimes even not possible. In this paper the most relevant parameters are outlined, by means of a derivation of the dimensionless 1-D AMR equations. The resulting reduced number of key parameters simplifies the performance optimization procedure. Moreover, if the proposed dimensionless set of parameters is reported each time in corresponding scientific work, a comparison of experimental or/and numerical results would become much more feasible and easy to be performed.
