    • On the miscibility of PVDF/PMMA polymer blends: Thermodynamics, experimental and numerical investigations 
      Article dans une revue avec comité de lecture
      AID, Sara; EDDHAHAK, Anissa; ORTEGA, Zaida; CHAABANI, Sana; ccTCHARKHTCHI, Abbas; ccKHELLADI, Sofiane (Elsevier, 2019)
      In this paper the miscibility of PVDF/PMMA blends was studied using different approaches: experimental tests, thermodynamics and numerical simulation. The first part of this study is devoted to the experimental work and ...
    • Time-averaged second-order pressure and velocity measurements in a pressurized oscillating flow prime mover 
      Article dans une revue avec comité de lecture
      PARIDAENS, Richard; ccKOUIDRI, SMAINE; JERBI, Fathi Jebali (Springer, 2016)
      Nonlinear phenomena in oscillating flow devices cause the appearance of a relatively minor secondary flow known as acoustic streaming, which is superimposed on the primary oscillating flow. Knowledge of control parameters, ...
    • Analysis and Comparison of Transonic Buffet Phenomenon over Several Three-Dimensional Wings 
      Article dans une revue avec comité de lecture
      PALADINI, Edoardo; DANDOIS, Julien; SIPP, Denis; ccROBINET, Jean-Christophe (American Institute of Aeronautics and Astronautics, 2019)
      The transonic buffet is a complex aerodynamic instability that appears on wings and airfoils at a high subsonic Mach number and/or angle of attack. It consists of a shock oscillation that induces pressure and notably lift ...
    • A very accurate Arbitrary Lagrangian–Eulerian meshless method for Computational Aeroacoustics 
      Article dans une revue avec comité de lecture
      RAMÍREZ, Luis; NOGUEIRA, Xesús; KRIMI, Abdelkader; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, we propose a new meshless approach based on a Galerkin discretization of a set of conservation equations on an Arbitrary Lagrangian–Eulerian framework. In particular, we solve the Linearized Euler Equations, ...
    • Modelling of sintering during rotational moulding of the thermoplastic polymers 
      Article dans une revue avec comité de lecture
      HAMIDI, A.; FARZANEH, Sedigheh; NONY, Fabien; ORTEGA, Zaida; MONZON, M.; ccTCHARKHTCHI, Abbas; ccBAKIR, Farid; ccKHELLADI, Sofiane (Springer Verlag, 2015)
      This paper concerns the study of sintering phenomenon during rotational molding of polypropylene(PP),Polyvinylidenefluoride (PVDF) and Polymethyl methacrylate (PMMA). First, the coalescence (first step of sintering) of two ...
    • Nonlinear optimal large-scale structures in turbulent channel flow 
      Article dans une revue avec comité de lecture
      FARANO, Mirko; CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Elsevier, 2018)
      Coherent structures in turbulent shear flows take the form of packets of hairpin vortices reaching the outer region of the boundary layer along with streaks of different size, going from the near-wall to the outer region. ...
    • Efficiency of bio- and socio-inspired optimization algorithms for axial turbomachinery design 
      Article dans une revue avec comité de lecture
      AIT CHIKH, Mohamed Abdessamed; BELAIDI, Idir; PARIS, José; ccDELIGANT, Michael; ccBAKIR, Farid; ccKHELLADI, Sofiane (Elsevier, 2018)
      Turbomachinery design is a complex problem which requires a lot of experience. The procedure may be speed up by the development of new numerical tools and optimization techniques. The latter rely on the parameterization ...
