A Computational fluid dynamics study on the effect of carbon particle seeding for the improvement of solar reactor performance / Nesrin Ozalp in Journal of heat transfer, Vol. 132 N° 12 (Décembre 2010) 

Public ISBD [article]  in Journal of heat transfer > Vol. 132 N° 12 (Décembre 2010) . - pp. [122901-1/7] Titre : A Computational fluid dynamics study on the effect of carbon particle seeding for the improvement of solar reactor performance Type de document : texte imprimé Auteurs : Nesrin Ozalp, Auteur ; Anoop Kanjirakat, Auteur Année de publication : 2010 Article en page(s) : pp. [122901-1/7] Note générale : Physique Langues : Anglais (eng) Mots-clés : Computational  flow  dynamics  Solar  reactor  Carbon  seeding  Solar  cracking  Hydrogen Index. décimale : 536 Chaleur. Thermodynamique Résumé : This study focuses on a technique, referred to as “solar cracking” of natural gas for the coproduction of hydrogen and carbon as byproduct with zero emission footprint. Seeding a solar reactor with micron-sized carbon particles increases the conversion efficiency drastically due to the radiation absorbed by the carbon particles and additional nucleation sites formed by carbon particles for heterogeneous decomposition reaction. The present study numerically tries to investigate the above fact by tracking carbon particles in a Lagrangian framework. The results on the effect of particle loading, particle emissivity, injection point location, and effect of using different window screening gases on a flow and temperature distribution inside a confined tornado flow reactor are presented.
