Titre : Coupled effects of surface-radiation and buoyancy on jet-impingement heat transfer Type de document : texte imprimé Auteurs : S. Abishek, Auteur ; R.

Note générale : heat transfer Langues : Anglais (eng) Mots-clés : radiation  jet-impingement  buoyancy  convection  laminar Index. décimale : 536 Chaleur. Thermodynamique Résumé : This paper delineates the results of an investigation on the combined effects of buoyancy and surface-radiation on heat transfer from an isothermal surface, subjected to a confined submerged impinging air-jet issuing from a slot-nozzle. The nondimensionalized governing equations are solved using the stream function-vorticity approach and an upwind finite-difference technique, employing the radiosity-irradiation formulation for surface-radiation. The effects of jet Reynolds number, dimensionless nozzle-to-heater distance, radiation-flow interaction parameter, Richardson number, and surface-emissivity, on the convective, radiative, and total Nusselt numbers, are analyzed for 100 DEWEY : 536 ISSN : 0022-1481 En ligne : http://asmedl.org/getabs/servlet/GetabsServlet?prog=normal&id=JHTRAO000134000008 [...] [article] Coupled effects of surface-radiation and buoyancy on jet-impingement heat transfer [texte imprimé] / S.
