Study on flow and heat transfer characteristics of ice slurry in the transition region / Hiroyuki Kumano 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. 801–808 Titre : Study on flow and heat transfer characteristics of ice slurry in the transition region Titre original : Etude sur l'écoulement et les caractéristiques des coulis de glace dans la zone de transition Type de document : texte imprimé Auteurs : Hiroyuki Kumano, Auteur ; Fumito Tamura, Auteur ; Seigo Sawada, Auteur Année de publication : 2013 Article en page(s) : pp. 801–808 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Ice  slurry;  Two-phase  flow;  Pressure  drop;  Heat  transfer  coefficient;  Non-Newtonian  fluid Résumé : The flow and heat transfer characteristics of ice slurry were investigated experimentally. The characteristics in the transition region were examined in detail. The ice slurry was produced from ethanol solution. Ice packing factor (IPF), Reynolds number and tube diameter were varied as experimental parameters, and the coefficients of pipe friction and heat transfer were measured. In the low IPF region, the coefficients of the pipe friction and heat transfer were found to be constant with values that were the same as for turbulent flow in an ethanol solution. However, for the high IPF region, laminarization occurs and flow and heat transfer characteristics can be estimated from the laminar flow of the ice slurry. Moreover, the laminarization point can be estimated using the apparent Reynolds number.
