    • An efficient reduced-order method with PGD for solving journal bearing hydrodynamic lubrication problems 
      Article dans une revue avec comité de lecture
      CHERABI, Bilal; HAMRANI, Abderrachid; BELAIDI, Idir; ccBAKIR, Farid; ccKHELLADI, Sofiane (Elsevier Masson, 2016)
      In the present work, a reduced-order method, “Proper Generalized Decomposition (PGD)” is extended and applied to the resolution of the Reynolds equation describing the behavior of the lubricant in hydrodynamic journal ...
    • Study of Bonding Formation between the Filaments of PLA in FFF Process 
      Article dans une revue avec comité de lecture
      KALLEL, Achraf; ccKOUTIRI, Imade; BABAEITORKAMANI, E.; KHAVANDI, A.; TAMIZIFAR, M.; ccSHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas (2019)
      Fused filament fabrication (FFF) is an additive manufacturing (AM) process that provides physical objects commonly used for modeling, prototyping and production applications. The major drawback of this process is poor ...
    • 1/f noise and long-term memory of coherent structures in a turbulent shear flow 
      Article dans une revue avec comité de lecture
      GISSINGER, C.; FAUVE, S.; ccPEREIRA, Michaël (American Physical Society (APS), 2019)
      A shear flow of liquid metal (Galinstan) is driven in an annular channel by counter-rotating traveling magnetic fields imposed at the endcaps. When the traveling velocities are large, the flow is turbulent and its azimuthal ...
    • Damping coefficient estimation of a squeeze-film damper operating in a dual shaft test rig 
      Article dans une revue avec comité de lecture
      GIBERT, Claude; SANCHEZ, Lionel; THOUVEREZ, Fabrice; ccGUSKOV, Mikhail (EDP Sciences, 2010)
      Squeeze film dampers (SFD) are used to reduce dynamical loads in rotating machinery or to improve their performances in numerous industrial applications. The present paper considers the response of a dual shaft system with ...
    • Flow and air-entrainment around partially submerged vertical cylinders 
      Article dans une revue avec comité de lecture
      AGEORGES, Valentin; PEIXINHO, Jorge; PÉRRET, Gaële (American Physical Society, 2019)
      In this study, a partially submerged vertical cylinder is moved at constant velocity through water, which is initially at rest. During the motion, the wake behind the cylinder induces free-surface deformation. Eleven ...
    • Effects of finishing processes on the fatigue life improvements of electro-machined surfaces of tool steel 
      Article dans une revue avec comité de lecture
      GHANEM, Farhat; FREDJ, Nabil Ben; SIDHOM, Habib; ccBRAHAM, Chedly (Springer Verlag, 2011)
      Machining the EN X160CrMoV12 tool steel by electro-discharge machining (EDM) process generates significant modifications of microgeometrical, microstructural and mechanical properties of the upper layers of the machined ...
    • Radiation aging and chemi-crystallization processes in polyoxymethylene 
      Article dans une revue avec comité de lecture
      VERDU, Jacques; ccFAYOLLE, Bruno (Elsevier, 2011)
      The radiochemical degradation of a polyoxymethylene homopolymer (POM) was used to study the effects of molar mass changes in the crystalline structure. The dose rate was 20 kGy h -1 with doses of up to 30 kGy used. Both ...
