Public ISBD [article]  inJournal of heat transfer > Vol. 134 N° 1 (Janvier 2012) . - 05 p. Titre : Falling film of ionic liquid-water binary solutions on a uniformly heated vertical wall Type de document : texte imprimé Auteurs : Jing Peng, Auteur ; Ming-Ming Wang, Auteur ; Jiao Geng, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : Heat transfer Langues : Anglais (eng) Mots-clés : Boundary layers Convection Film flow Flow visualisation Organic compounds Pattern formation Water Index. décimale : 536 Chaleur. Thermodynamique Résumé : The flow characteristics of falling film of amino acid ionic liquid (AAIL) aqueous solution on a uniformly heated vertical plane have been experimentally studied. The infrared images and temperature profiles have been determined and used to analyze the fluid flow. It is proven that the Marangoni effect exists widely and has significant influence on the flow region of falling film. A novel flow pattern is additionally observed when the mass fraction of AAIL is 30%. The flow patterns are also shown to be affected by the wall-liquid temperature differential, the flow rate and the concentration of solute. The experimental results of AAIL falling film are expected to be helpful for the further industrial application of ionic liquids.
