Fast liquid jet mixing in millimeter channels with various multislits designs / Zhe Liu in Industrial & engineering chemistry research, Vol. 47 N° 23 (Décembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N° 23 (Décembre 2008) . - p. 9744–9753 Titre : Fast liquid jet mixing in millimeter channels with various multislits designs Type de document : texte imprimé Auteurs : Zhe Liu, Auteur ; Yi Cheng, Auteur ; Yong Jin, Auteur Année de publication : 2009 Article en page(s) : p. 9744–9753 Note générale : Chemistry engineering Langues : Anglais (eng) Mots-clés : Liquid  jet  Millimeter  channels Résumé : The jet flow mixers in which fluids are mixed in the confined millimeter-sized channels were further studied to better understand the fast liquid mixing process and the means to intensify the mixing performance. Four mixer designs with different modifications on the local configuration for adjusted contact mode between liquids were investigated by visualizing the mixing processes using planar laser-induced fluorescence (PLIF) technique. A large amount of experiments with various operating conditions were carried out for all the four designs. The common feature in all the cases was that the two liquids can be mixed well in milliseconds, where the momentum ratio between the bulk and the jet flows played a significant role in the mixing performance. The results also demonstrated that the contact mode between the two liquids had a great effect on the mixing performance. By dividing the side-jet liquid stream into several smaller aperture-jets, the mixing process can be clearly improved, which can be attributed to the increased contact area and the higher velocity difference between the two liquids.
