    • Influence de la répartition de la charge sur les performances d'une turbomachine axiale contrarotative 
      Communication avec acte
      WANG, Juan; ccRAVELET, Florent; ccSARRAF, Christophe; ccBAKIR, Farid (2013)
      Due to high requirements of energy consumption level, weight and dimension restriction in many industrial fields, compact axial turbomachines are expected. Counter-rotating axial-flow fans may be a solution. The design and ...
    • An ageing elasto-viscoplastic model for ceramics 
      Article dans une revue avec comité de lecture
      SOULACROIX, Julian; MICHEL, Bruno; GATT, Jean-Marie; ccBARRALLIER, Laurent; ccKUBLER, Regis (Elsevier, 2014)
      A model reproducing strain softening behavior in ceramic materials is proposed, base on a critical treatment of previous mechanical experimental results on uranium dioxide. The main hypothesis is that the strain softening ...
    • Study of interpolation methods for high-accuracy computations on overlapping grids 
      Article dans une revue avec comité de lecture
      CHICHEPORTICHE, Jérémie; ccGLOERFELT, Xavier (Elsevier, 2012)
      Overset strategy can be an efficient way to keep high-accuracy discretization by decomposing a complex geometry in topologically simple subdomains. Apart from the grid assembly algorithm, the key point of overset technique ...
    • Kinematic Alpha Tensors and dynamo mechanisms in a von Karman swirling flow 
      Article dans une revue avec comité de lecture
      DUBRULLE, Bérengère; DAVIAUD, François; RATIÉ, Pierre-Arthur; ccRAVELET, Florent (American Physical Society, 2012)
      We provide experimental and numerical evidence of in-blades vortices in the von Karman swirling flow. We estimate the associated kinematic α-effect tensor and show that it is compatible with recent models of the von Karman ...
    • Study of passive control study of the cavitation instability on a venturi profile 
      Communication avec acte
      DANLOS, Amélie (2012)
      As a source of vibrations, noise, erosion and structure damages, cavitation is a major handicap for many industrial flows used in different domains from propeller or pump studies, to the analysis of hydrodynamic flows ...
    • Study of the cavitating instability on a grooved Venturi profile 
      Article dans une revue avec comité de lecture
      DANLOS, Amélie; MÉHAL, Jean-Elie; ccRAVELET, Florent; ccCOUTIER-DELGOSHA, Olivier; ccBAKIR, Farid (American Society of Mechanical Engineers, 2014)
      Instabilities of a partial cavity developed on a hydrofoil, a converging-diverging step, or in an interblade channel have already been investigated in many previous works. The aim of this study is to evaluate a passive ...
    • Experimental analysis of the pressure–velocity correlations of external unsteady flow over rocket launchers 
      Article dans une revue avec comité de lecture
      MARIÉ, Simon; DRUAULT, Philippe; LAMBARE, Hadrien; SCHRIJER, Ferry (Elsevier, 2013)
      Based on simultaneous wall pressure and velocity measurements, the aerodynamic load of a launcher body model is investigated. Two different configurations are considered in order to study the influence of geometrical ...
