Investigation of the influence of surfactant on the degree of supercooling (coexisting system of solid–liquid and gas–liquid interfaces) / Koji Matsumoto in International journal of refrigeration, Vol. 36 N° 4 (Juin 2013) 

Public ISBD [article]  in International journal of refrigeration > Vol. 36 N° 4 (Juin 2013) . - pp. 1302–1309 Titre : Investigation of the influence of surfactant on the degree of supercooling (coexisting system of solid–liquid and gas–liquid interfaces) Titre original : Etude sur l'influence de l'agent tensio-actif sur le degré de surrefroidissement (système où les interfaces solide/liquide et gaz/liquide coexistent) Type de document : texte imprimé Auteurs : Koji Matsumoto, Auteur ; Yoshito Igarashi, Auteur ; Daisuke Shirai, Auteur Année de publication : 2013 Article en page(s) : pp. 1302–1309 Note générale : Refrigeration Langues : Anglais (eng) Mots-clés : Ice  formation;  Surfactant;  Critical  micelle  concentration;  Supercooling Résumé : In the ice formation process, supercooling, which results in COP degradation of the ice formation system, is avoidable. Thus, controlling supercooling dissolution would provide numerous benefits to the ice formation system. In order to control supercooling dissolution, we focus on the characteristics of hydrophilic surfactants. When hydrophilic surfactant is added to water, it is a great possibility that hydrophobic (lipophilic) surfactant molecules are adsorbed at gas–liquid and solid–liquid interfaces. Adsorption is assumed to affect supercooling dissolution. In the present study, in a coexisting system of solid–liquid and gas–liquid interfaces, a mixture of pure water and a small amount of hydrophilic surfactant is cooled in a test tube, the influence of the surfactant on the degree of supercooling of the mixture is clarified, and the tendencies of the degree of supercooling of the mixture above and below the critical micelle concentration are clarified.
