Public ISBD [article]  inTransactions of the ASME . Journal of fluids engineering > Vol. 131 N° 11 (Novembre 2009) . - 06 p. Titre : Application of MI simulation using a turbulent model for unsteady orifice flow Type de document : texte imprimé Auteurs : Mitsuhiro Nakao, Auteur ; Kenji Kawashima, Auteur ; Toshiharu Kagawa, Auteur Année de publication : 2010 Article en page(s) : 06 p. Note générale : fluids engineering Langues : Anglais (eng) Mots-clés : pressure  flow (dynamics)  simulation  feedback  turbulence Résumé : Measurement-integrated (MI) simulation is a numerical simulation in which experimental results are fed back to the simulation. The calculated values become closer to the experimental values. In the present paper, MI simulation using a turbulent model is proposed and applied to steady and unsteady oscillatory airflows passing an orifice plate in a pipeline. Velocity and pressure feedbacks are conducted and both feedback methods showed good agreement with the experimental results. Moreover, the calculation times between the MI simulation and ordinary simulation were compared in steady and unsteady conditions. The calculation time was demonstrated to be significantly reduced compared with ordinary simulation.
