Correlation of subatmospheric pressure, saturated, pool boiling of water on a structured-porous surface / Sean J. Penley in Journal of heat transfer, Vol. 133 N° 4 (Avril 2011) 

Public ISBD [article]  in Journal of heat transfer > Vol. 133 N° 4 (Avril 2011) . - pp. [041501/1-11] Titre : Correlation of subatmospheric pressure, saturated, pool boiling of water on a structured-porous surface Type de document : texte imprimé Auteurs : Sean J. Penley, Auteur ; R. A. Wirtz, Auteur Année de publication : 2011 Article en page(s) : pp. [041501/1-11] Note générale : Physique Langues : Anglais (eng) Mots-clés : Boilling  Enhanced  surface  Subatmospheric  pressure  Correlation  Water  nucleation  Structured-porous  surface  Screen  laminate  Thermal  management  Electronic  cooling Index. décimale : 536 Chaleur. Thermodynamique Résumé : Saturated pool-boiling experiments at 1 atm and subatmospheric pressure assess the utility of fine-filament screen-laminate enhanced surfaces as effective bubble nucleation sites. Experiments were conducted on vertically oriented, multilayer laminates in saturated distilled water at pressures of 0.2–1.0 atm. The performance of 12 different copper-filament surfaces, having pore hydraulic diameters ranging from 14 µm to 172 µm, is documented. Experimental results show that boiling performance is a strong function of screen-laminate geometry. In the present work, enhancement of up to 27 times that of an unenhanced surface was obtained at a superheat of 8 K and a pressure of 0.2 atm. Dimensional analysis and multiparameter regression are used to develop a heat transfer correlation that relates the boiling heat transfer coefficient to the lamination geometry.
