Public ISBD [article]  in International journal of refrigeration > Vol. 33 N° 8 (Décembre 2010) . - pp. 1533-1539 Titre : Effect of temperature on the effective latent heat of fusion of ice in aqueous solutions Titre original : Effet de la température sur la chaleur latente de fusion de glace dans les solutions aqueuses Type de document : texte imprimé Auteurs : Tatsunori Asaoka, Auteur ; Hiroyuki Kumano, Auteur ; Masashi Okada, Auteur Année de publication : 2011 Article en page(s) : pp. 1533-1539 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Thermodynamic  Melting  Ice  Aqueous  solution  Latent  heat  Parameter  Temperature Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The calculation method for the effective latent heat of fusion of ice in aqueous solution was proposed, in order to clarify the amount of heat generated by the melting of ice in ice slurry. In this study, the effect of the temperature of the aqueous solution on the effective latent heat was investigated. As a result, it was clarified that the effective latent heat of fusion of ice in ethanol solution is significantly affected by the temperature of the solution, thought not so significantly for propylene glycol and ethylene glycol solutions. Additionally, the specific heat of ethanol solution near the freezing temperature was measured, since there are insufficient data for our investigations. Moreover, the investigation to estimate the effective latent heat near the freezing temperature was carried out.

Fundamental study on melting of the ice particle bed due to inflow of warm water / Tatsunori Asaoka 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. 852–861 Titre : Fundamental study on melting of the ice particle bed due to inflow of warm water : effect of the initial shape of the ice particle bed on melting behavior Titre original : Etude fondamentale sur la fusion du lit de particules de glace suite à un afflux d'eau chaude : effet de la forme initiale du lit de particules de glace sur le comportement de fusion Type de document : texte imprimé Auteurs : Tatsunori Asaoka, Auteur ; Hiroyuki Kumano, Auteur ; Masashi Okada, Auteur Année de publication : 2013 Article en page(s) : pp. 852–861 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Thermal  storage;  Melting;  Ice;  Heat  transfer Résumé : Fine ice particles that make up an ice slurry have an advantage in heat transfer and melt rapidly because of their large specific surface area. In a dynamic-type ice storage system, an ice particle bed is melted by warm water flowing through it to obtain cooled water. The melting process generates a wide flow channel, causing a temperature rise in the ejected water and residual unmelted ice. The melting shape of an ice particle bed depends on the initial shape and the inhomogeneity of porosity in it. This study examined the effect of the initial shape of the ice particle bed on the melting behavior to thereby control the melting shape. The melting shape was controlled by establishing a gap on the surface of the ice particle bed. The pressure distribution in the ice bed varied with the size of the gap, and it strongly affected the melting shape.
