    • A new cavitation model based on bubble-bubble interactions 
      Article dans une revue avec comité de lecture
      ADAMA MAIGA, Mahamadou; BUISINE, Daniel; ccCOUTIER-DELGOSHA, Olivier (American Institute of Physics, 2018)
      In this paper, a new model based on bubble-bubble interactions is proposed for cavitation. Unlike the well-known existing models (Rayleigh-Plesset, Gilmore), which are derived from the local balance equations in the vicinity ...
    • Cavitation Dynamics at Sub-Millimeter Scale 
      Communication avec acte
      LONG, Kunpeng; DULAR, Matevž; ccCOUTIER-DELGOSHA, Olivier (ASME Press, 2018)
      This paper is focused on the dynamics of cloud cavitation at Sub-millimeter scales, between 0.1 and 10 mm. A simple flow configuration consisting in a small diameter jet impacting a wall at 90° and then flowing radially ...
    • Numerical Investigation of the Effects of Nonsinusoidal Motion Trajectory on the Propulsion Mechanisms of a Flapping Airfoil 
      Article dans une revue avec comité de lecture
      BOUDIS, A.; BENZAOUI, A.; OUALLI, H.; GUERRI, O.; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (American Society of Mechanical Engineers, 2019)
      The effect of nonsinusoidal trajectory on the propulsive performances and the vortex shedding process behind a flapping airfoil is investigated in this study. A movement of a rigid NACA0012 airfoil undergoing a combined ...
    • Canal lock variable speed hydropower turbine design and control 
      Article dans une revue avec comité de lecture
      ZHANGH, Jian; LEONTIDIS, Vlasios; TOUNZI, Abdelmounaim; DELARUE, Phillipe; CAIGNAERT, Guy; PIRIOU, Francis; LIBAUX, Antoine; ccDAZIN, Antoine (Wiley, 2018)
      The design of a novel submerged hydraulic turbine for producing electricity by converting the available hydropower on canal locks during raising and lowering ships, but with the minimum overall impact on the facility, is ...
    • Modeling dynamic systems : contribution to the unsteady behavior of a condenser based on the pseudo-bond graph approach 
      Article dans une revue avec comité de lecture
      KEBDANI, Mohamed; DAUPHIN-TANGUY, Geneviève; ccDAZIN, Antoine (ACTA Press, 2018)
      This article is devoted to the dynamic study of the brazed plate condenser (BPC). The proposed model is based on the bond graph theory. The proposed model is based on the bond graph theory because of its energetic approach ...
    • Static pressure recovery analysis in the vane island diffuser of a centrifugal pump 
      Article dans une revue avec comité de lecture
      SI, Qiaorui; DUPONT, Patrick; ccBAYEUL-LAINÉ, Annie-Claude; ccDAZIN, Antoine; ROUSSETTE, Olivier; BOIS, Gérard (Springer, 2016)
      The overall performance of a vane-island type diffuser of a centrifugal pump model was obtained by means of directional probe traverses. These measurements were performed in an air model of a real hydraulic pump for five ...
    • Energy extraction performance improvement of a flapping foil by the use of combined foil 
      Article dans une revue avec comité de lecture
      BOUDIS, Ali; BENZAOUI, Ahmed; OUALLI, H; GUERRI, O; ccCOUTIER-DELGOSHA, Olivier; ccBAYEUL-LAINÉ, Annie-Claude (Elsevier, 2018)
      In this study, numerical investigations on the energy extraction performance of a flapping foil device are carried out by using a modified foil shape. The new foil shape is designed by combining the thick leading edge of ...
