Thermodynamic effect on a cavitating inducer in liquid hydrogen / Eric Goncalvès in Transactions of the ASME . Journal of fluids engineering, Vol. 132 N° 11 (Novembre 2010)  

Public ISBD [article]  inTransactions of the ASME . Journal of fluids engineering > Vol. 132 N° 11 (Novembre 2010) . - 07 p. Titre : Thermodynamic effect on a cavitating inducer in liquid hydrogen Type de document : texte imprimé Auteurs : Eric Goncalvès, Auteur ; Regiane Fortes Patella, Auteur ; Julien Rolland, Auteur Année de publication : 2011 Article en page(s) : 07 p. Note générale : fluids engineering Langues : Anglais (eng) Mots-clés : pressure  flow (dynamics)  temperature  cooling  fluids  vapors  suction  cavitation  drops  blades  boundary-value problems  cavities  computation  equations  geometry  hydrogen  temperature distribution  wall water  heating Index. décimale : 620.1 Essais des matériaux. Défauts des matériaux. Protection des matériaux Résumé : This study was led in collaboration with the French Space Agency (CNES) and the Rocket Engine Division of Snecma. The main aims were the simulations and the analyses of cavitating flows in the rocket engine turbopump inducers, where the operating fluids are LH2 and LOx under cryogenic conditions. A ρ(P,T) state law modeling the cavitation phenomenon was integrated by the laboratory LEGI in the commercial computational fluid dynamics (CFD) code FINE/TURBO ™ , developed by Numeca International. Various 3D numerical results are given for an inducer geometry and comparisons are made with experimental data (head drop curves) obtained by NASA.
