    • 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.; SHIRINBAYAN, 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 ...
    • Silent inflow condition for turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ccROBINET, Jean-Christophe; ccGLOERFELT, Xavier (American Physical Society, 2017)
      The generation of a turbulent inflow is a tricky problem. In the framework of aeroacoustics, another important constraint is that the numerical strategy used to reach a turbulent state induces a spurious noise which is ...
    • Performance of hydrodynamic journal bearing under the combined influence of textured surface and journal misalignment: A numerical survey 
      Article dans une revue avec comité de lecture
      MANSER, Belkacem; BELAIDI, Idir; HAMRANI, Abderrachid; ccBAKIR, Farid; ccKHELLADI, Sofiane (Elsevier Masson, 2019)
      A wisely chosen geometry of micro textures with the favorable relative motion of lubricated surfaces in contacts can enhance tribological characteristics. In this paper, a computational investigation related to the combined ...
    • Multi-scale analysis of the effect of loading conditions on monotonic and fatigue behavior of a glass fiber reinforced polyphenylene sulfide (PPS) composite 
      Article dans une revue avec comité de lecture
      ZUO, Peiyuan; BENEVIDES, R.C.; LARIBI, M.A.; SHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas; ccFITOUSSI, Joseph; ccBAKIR, Farid (Elsevier, 2018)
      In this paper, two kinds of PPS/GF composite samples (PPS-0°, PPS-90°) were prepared with two different fiber main orientations related to the injection direction. A wide range of their properties were discussed. Using ...
    • A New Hemodynamic Ex Vivo Model for Medical Devices Assessment 
      Article dans une revue avec comité de lecture
      MAUREL, Blandine; CHAI, Feng; MATON, Mickael; SOBOCINSKI, Jonathan; HERTAULT, Adrien; BLANCHEMAIN, Nicolas; HAULON, Stephan; LERMUSIAUX, Patrick; ccSARRAF, Christophe; ccBAKIR, Farid (Elsevier Masson, 2015)
      Introduction: In stent restenosis (ISR) remains a major public health concern with an increased morbidity, mortality and health-related costs. Drug-eluting stents (DES) have reduced ISR, but are associated with healing-related ...
