Two-dimensional simulation of the collapse of vapor bubbles near a wall / Luo Jing in Transactions of the ASME . Journal of fluids engineering, Vol. 130 N° 9 (Septembre 2008)  

Public ISBD [article]  inTransactions of the ASME . Journal of fluids engineering > Vol. 130 N° 9 (Septembre 2008) . - 4 p. Titre : Two-dimensional simulation of the collapse of vapor bubbles near a wall Type de document : texte imprimé Auteurs : Luo Jing, Auteur ; Jian Li, Auteur ; Dong Guangneng, Auteur Année de publication : 2009 Article en page(s) : 4 p. Note générale : Fluids engineering Langues : Anglais (eng) Mots-clés : Vapor bubbles  two dimensional simulation Résumé : In order to investigate the erosion extent and mode of cavitation in different states by the commercial code FLUENT and evaluate the reliability of the software, the collapse processes of a vapor bubble, which was near or on the wall under the conditions in the stationary water or the high speed water, were simulated by the numerical calculation by using a 2D model. The results are in accordance with results presented by other researchers, so the simulation may testify to the validation of the code. We suppose that a bevel jet, which is generated contrary to the flow direction when the bubble collapses in high speed flow, may cause the ripple and fish-scale pit damage found on the transition parts of many hydraulic systems.
