Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 26 (Juillet 2012) . - pp. 9153-9163 Titre : Numerical simulation of a turbulent confined slot impinging jet Type de document : texte imprimé Auteurs : Shantanu Pramanik, Auteur ; A. Madhusudana Achari, Auteur ; Manab Kumar Das, Auteur Année de publication : 2012 Article en page(s) : pp. 9153-9163 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Numerical  simulation Résumé : A detailed numerical study has been conducted for a two-dimensional, steady, incompressible, single confined turbulent slot jet impinging normally on a flat plate. The standard high Reynolds number two-equation k―ε eddy viscosity model has been used as the turbulence model. The separation between the jet-impingement surface and the confinement surface is varied from 2 to 20; however, detailed results are shown for 6.0. The turbulence intensity and the Reynolds number at the inlet are 2% and 11000 respectively. The mean flow and turbulent characteristics have been investigated. The distribution of streamwise mean velocity, static pressure, and turbulence have been presented for thorough understanding of the flow field. The integral of mean momentum, pressure, and turbulence fluctuation have been computed along the direction of flow. The locations of the reattachment point and center of the recirculating vortex have also been determined. A similarity profile was observed downstream of the reattachment point. A detailed discussion is provided on the pressure field, Reynolds stress, and kinetic energy and its dissipation rate.
