    • A combined numerical/experimental analysis of the flow in the channel of the vaned diffuser of a radial flow pump 
      Article dans une revue avec comité de lecture
      DUPONT, Patrick; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (IOP Publishing, 2019)
      The realization and the validation of a simulation in fluid mechanics require an indepth expertise of the modelling process. However, how could the results be guaranteed if they were not accompanied by experimental ...
    • Numerical investigation of the effect of motion trajectory on the vortex shedding process behind a flapping airfoil 
      Communication avec acte
      BOUDIS, Ali; BENZAOUI, Ahmed; OUALLI, Hamid; GUERRI, Ouahiba; ccBAYEUL-LAINÉ, Annie-Claude (ISROMAC 2017, 2017)
      The effect of non-sinusoidal trajectory on the propulsive performances and the vortex shedding process behind a flapping airfoil is investigated in this study. A movement of a rigid NACA 0012 airfoil undergoing a combined ...
    • Model based analysis of the time scales associated to pump start-ups 
      Article dans une revue avec comité de lecture
      CAIGNAERT, Guy; DAUPHIN-TANGUY, Geneviève; ccDAZIN, Antoine (Elsevier, 2015)
      The paper refers to a non dimensional analysis of the behaviour of a hydraulic system during pump faststart-ups. The system is composed of a radial flow pump and its suction and delivery pipes. It is modelled using the ...
    • Experimental validation of an ultrasonic flowmeter for unsteady flows 
      Article dans une revue avec comité de lecture
      LEONTIDIS, Vlasios; CUVIER, Christophe; CAIGNAERT, Guy; DUPONT, Patrick; ROUSSETTE, Olivier; FAMMERY, Simon; NIVET, P.; ccDAZIN, Antoine (IOP Publishing, 2018)
      An ultrasonic flowmeter was developed for further applications in cryogenic conditions and for measuring flow rate fluctuations in the range of 0 to 70 Hz. The prototype was installed in a flow test rig, and was validated ...
    • 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 ...
    • A study of rotating stall in a vaneless diffuser of radial flow pump 
      Article dans une revue avec comité de lecture
      HENG, Yaguang; OUARZAZI, Mohamed Najib; SI, Qiaorui; ccDAZIN, Antoine (Taylor & Francis, 2018)
      Rotating stall in a vaneless diffuser of radial flow pump is studied. The measurements consist of: (i) unsteady pressure measurements delivered by two microphones; and (ii) nine steady pressure taps mounted in one radial ...
    • 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 ...
