Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 23 (Décembre 2011) . - pp. 13230-13235 Titre : Liquid – liquid mixing in coiled flow inverter Type de document : texte imprimé Auteurs : Monisha Mridha Mandal, Auteur ; Palka Aggarwal, Auteur ; K. D. P. Nigam, Auteur Année de publication : 2012 Article en page(s) : pp. 13230-13235 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Mixing Résumé : The mixing of liquids is a common operation in process industries such as refineries and chemical and pharmaceutical industries, etc. However, the problem of mixing of different liquids has not been rigorously characterized. Therefore, the objective of this paper is to investigate liquid―liquid mixing in a novel coiled flow inverter (CFI). The device works on the principle of flow inversion which is achieved by bending a coiled tube to 90° at equidistant length. In the present study, velocity field and scalar concentration distribution of liquids were characterized. The mixing performances and pressure drop in CFI was investigated and compared with that of a straight, coiled tube and helical element mixer (HEM) for a liquid flow range of 98 ≤ Re ≤ 1020. CFI exhibits significant mixing of two liquids with negligible change in pressure drop as compared to a coiled tube as well as a HEM. The present study reveals that CFI is an efficient device for the mixing of two liquids in process industries.
