Mandal, Auteur ; Gargi Das, Auteur ; Prasanta K. Das, Auteur Année de publication : 2008 Article en page(s) : p. 7048–7057 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Liquid Taylor bubbles drops Inclined tubes Vertical Liquid-liquid systems Résumé : The present work reports an experimental study on the shape and stability of liquid Taylor bubbles and liquid Taylor drops in vertical and inclined tubes. Experiments have been performed with five liquid pairs, namely, water−kerosene, brine−kerosene, water−benzene, water−cyclohexane, and water−2-heptanone, in five different tube diameters ranging from 0.012 to 0.046 m and inclinations of 0°, 15°, 30°, 45°, 60°, and 75° with vertical. The effect of tube inclination, tube diameter, and pipe material on shape, stability, and velocity of a liquid Taylor bubbles and liquid Taylor drops has been explained qualitatively from basic physics. The existing correlations generally used for gas−liquid system have been modified to predict the rise velocity in vertical tubes.
