Radial dispersion in liquid upflow through solid SiC foams / Tri Truong Huu in Industrial & engineering chemistry research, Vol. 50 N° 8 (Avril 2011)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 8 (Avril 2011) . - pp. 4329–4334 Titre : Radial dispersion in liquid upflow through solid SiC foams Type de document : texte imprimé Auteurs : Tri Truong Huu, Auteur ; Regis Philippe, Auteur ; Patrick Nguyen, Auteur Année de publication : 2011 Article en page(s) : pp. 4329–4334 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Radial dispersion Résumé : The radial dispersion process of an inert tracer in an upward liquid flow (superficial velocity from 3 × 10−3 to 13 × 10−3 m·s−1) through high-porosity (0.85 and 0.90 void fractions) solid foam samples of various lengths (6−15 cm) has been investigated. As in a standard packed bed the radial Peclet number based on the “cell diameter” is found to be of the order of 10 when the process is governed by mechanical dispersion. The results are in agreement with the flow contribution to the effective radial heat conductivity measured independently on the same type of foams.
