    • Dynamic measurements of pressures, sail shape and forces on a full-scale spinnaker 
      Communication avec acte
      DEPARDAY, Julien; ccBOT, Patrick; ccHAUVILLE, Frederic; MOTTA, Dario; LE PELLEY, David; FLAY, Richard G.J. (2014)
      This work presents a full-scale experimental study on a sailing yacht in downwind conditions with simultaneous time-resolved measurements of pressures, sail shape and loads. Those on-water experiments on a J/80 class yacht ...
    • 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, ...
    • Multiple-correction hybrid k -exact schemes for high-order compressible RANS-LES simulations on fully unstructured grids 
      Article dans une revue avec comité de lecture
      PONT, Grégoire; BRENNER, Pierre; CINNELLA, Paola; MAUGARS, Bruno; ccROBINET, Jean-Christophe (Elsevier, 2017)
      A Godunov's type unstructured finite volume method suitable for highly compressible turbulent scale-resolving simulations around complex geometries is constructed by using a successive correction technique. First, a family ...
    • Dynamic Analysis of MMC-Based MTDC Grids : Use of MMC Energy to Improve Voltage Behavior 
      Article dans une revue avec comité de lecture
      FREYTES, Julian; AKKARI, Samy; RAULT, Pierre; BELHAOUANE, Mohamed Moez; COLAS, Frédéric; GUILLAUD, Xavier; ccGRUSON, Francois (Institute of Electrical and Electronics Engineers, 2019)
      This article deals with DC voltage dynamics of Multi-Terminal HVDC grids (MTDC) with energy-based controlled Modular Multilevel Converters (MMC) adopting the commonly used power-voltage droop control technique for power ...
    • Analytical study of the thermal degradation of poly(ether imide) 
      Article dans une revue avec comité de lecture
      COURVOISIER, Emilie; BICABA, Yoann; ccCOLIN, Xavier (EDP Sciences, 2017)
      The thermal degradation of PEI has been studied in wide ranges of temperature (between 180 and 250 °C) and oxygen partial pressure (between 0.21 and 50 bars). First of all, the thermal ageing mechanisms have been analysed ...
    • Data-Free and Data-Driven RANS Predictions with Quantified Uncertainty 
      Article dans une revue avec comité de lecture
      EDELING, Wouter Nico; IACCARINO, Gianluca; CINNELLA, Paola (Springer Verlag (Germany), 2017)
      For the purpose of estimating the epistemic model-form uncertainty in Reynolds-Averaged Navier-Stokes closures, we propose two transport equations to locally perturb the Reynolds stress tensor of a given baseline eddy-viscosity ...
