A dynamic film model of the pulsating heat pipe / Vadim S. Nikolayev in Journal of heat transfer, Vol. 133 N° 8 (Août 2011) 

Public ISBD [article]  in Journal of heat transfer > Vol. 133 N° 8 (Août 2011) . - pp. [081504/1-9] Titre : A dynamic film model of the pulsating heat pipe Type de document : texte imprimé Auteurs : Vadim S. Nikolayev, Auteur Année de publication : 2011 Article en page(s) : pp. [081504/1-9] Note générale : Physique Langues : Anglais (eng) Mots-clés : Oscillating  Pulsating  Heat  pipe  Simulation Index. décimale : 536 Chaleur. Thermodynamique Résumé : This article deals with the numerical modeling of the pulsating heat pipe (PHP) and is based on the film evaporation/condensation model recently applied to the single-bubble PHP (Das et al., 2010, “Thermally Induced Two-Phase Oscillating Flow Inside a Capillary Tube,” Int. J. Heat Mass Transfer, 53(19–20), pp. 3905–3913). The described numerical code can treat the PHP of an arbitrary number of bubbles and branches. Several phenomena that occur inside the PHP are taken into account: coalescence of liquid plugs, film junction or rupture, etc. The model reproduces some of the experimentally observed regimes of functioning of the PHP such as chaotic or intermittent oscillations of large amplitudes. Some results on the PHP heat transfer are discussed.
