    • 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 ...
    • "Low Cost" Approaches for the Prediction of Rotating Instabilities in the Vaneless Diffuser of a Radial Flow Pump 
      Ouvrage scientifique
      ZHOU, Banglun; YUAN, Jianping; HENG, Yaguang; DUPONT, Patrick; OUARZAZI, Najib; ccDAZIN, Antoine; ccBAYEUL-LAINÉ, Annie-Claude (Advances in Hydroinformatics, 2018)
      The instabilities, occurring in pumps operating at partial flow rates, may directly cause several negative effects, such as vibration, noise, mechanical damage. The present study is focused on the investigation of the ...
    • FSI Investigation on Stability of Downwind Sails with an Automatic Dynamic Trimming 
      Communication avec acte
      DURAND, Mathieu; LOTHODE, Corentin; ccHAUVILLE, Frederic; LEROYER, Alban; VISONNEAU, Michel; FLOCH, Ronan; GUILLAUME, Laurent (Ecole Navale, 2013)
      Gennakers are lightweight and flexible sails, used for downwind sailing configurations. Qualities sought for this kind of sail are propulsive force and dynamic stability. To simulate accurately the flow around such a sail, ...
    • Shot Peening Analysis on Trip780 Steel Exhibiting Martensitic Transformation 
      Communication avec acte
      GUIHEUX, Romain; BOUSCAUD, Denis; PATOOR, Etienne; PUYDT, Quentin; OSMOND, Pierre; WEBER, Bastien; ccBERVEILLER, Sophie; ccKUBLER, Regis (ShotPeener ICSP13, 2017)
      In the last years, due to increasing ecology and environmental constraints, a search for lightweight structures has been carried out, leading to the use of more complex geometries and new materials. In that context, TRIP ...
    • Bounds on size effects in composites via homogenization accounting for general interfaces 
      Article dans une revue avec comité de lecture
      FIROOZ, Soheil; CHATZIGEORGIOU, George; ccMERAGHNI, Fodil; JAVILI, Ali (Springer Verlag, 2019)
      This manuscript provides novel bounds and estimates, for the first time, on size-dependent properties of composites accounting for generalized interfaces in their microstructure, via analytical homogenization verified by ...
    • Piezoelectric resonant shunt enhancement by negative capacitances: Optimisation, performance and resonance cancellation 
      Article dans une revue avec comité de lecture
      BERARDENGO, Marta; MANZONI, Stefano; ccTHOMAS, Olivier; VANALI, Marcello (SAGE Publications, 2018)
      This article addresses piezoelectric shunt damping through a resonant shunt associated with negative capacitances. The main objective of this article is to provide guidelines for choosing the best electrical circuit layout ...
