    • Bayesian optimisation of RANS simulation with ensemble-based variational method in convergent-divergent channel 
      Article dans une revue avec comité de lecture
      ZHANG, Xinlei; GOMEZ, Thomas; ccCOUTIER-DELGOSHA, Olivier (Taylor & Francis, 2019)
      This paper investigates the applicability of a hybrid data assimilation approach, namely ensemble-based variational method (EnVar), to optimise Reynolds Averaged Navier-Stokes (RANS) simulations in convergent-divergent ...
    • Numerical study of a sinusoidal transverse propeller 
      Article dans une revue avec comité de lecture
      FASSE, Guillaume; CURUTCHET, A.; PAILLARD, B.; ccCOUTIER-DELGOSHA, Olivier; ccHAUVILLE, Frederic; ccBAYEUL-LAINÉ, Annie-Claude (IOP Publishing, 2019)
      In order to obtain higher propulsion efficiency for marine transportation, the authors have numerically tested a novel trochoidal propeller using a sinusoidal blade pitch function. The main results presented here are the ...
    • 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 ...
    • 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 ...
    • Investigations inside a vaned diffuser of a centrifugal pump at low flowrates. 
      Article dans une revue avec comité de lecture
      DUPONT, Patrick; BOIS, Gérard; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (IOP Publishing, 2016)
      This paper focuses on the unsteady flow behaviour inside the vaned diffuser of a radial flow pump model, operating at partial flowrates (0.387Qi, 0.584Qi and 0.766Qi where Qi is the impeller design flowrate).The effects ...
    • Measurements of the temperature variations during the growth and collapse of cavitation bubbles 
      Communication avec acte
      HAMDI, Merouan; BAUDOIN, Michael; ccCOUTIER-DELGOSHA, Olivier (ASME, 2018)
      The present work focuses on the analysis of the extreme conditions encountered during the process of collapse of cavitation bubbles. The objective is to characterize the temperature variations inside the vapor/gas bubble, ...
    • 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 ...
