Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 12 (Juin 2010) . - pp. 5877–5883 Titre : Stagnation point offset of two opposed jets Type de document : texte imprimé Auteurs : Zhi-gang Sun, Auteur ; Wei-feng Li, Auteur ; Hai Feng Liu, Auteur Année de publication : 2010 Article en page(s) : pp. 5877–5883 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Axial velocity Stagnation point offset Impinging streamsSmoke wire visualization Hot-wire anemometry techniques Résumé : The axial velocity and the stagnation point offset of impinging streams from two opposed nozzles have been theoretically studied and experimentally measured by smoke wire visualization and hot-wire anemometry (HWA) techniques. The results show that, for small nozzle separation (L/D 12), the equations based on the free jet theory can be used to predict the stagnation point offset for two nozzles of the same and different sizes. The illustrated effects of the exit momentum ratio and the nozzle separation on the stagnation point offset are useful for defining the optimum conditions for many industrial applications of the opposed jets.
