    • New high-resolution-preserving sliding mesh techniques for higher-order finite volume schemes 
      Article dans une revue avec comité de lecture
      RAMÍREZ, Luis; FOULQUIÉ, Charles; NOGUEIRA, Xesús; CHASSAING, Jean-Camille; COLOMINAS, Ignasi; ccKHELLADI, Sofiane (Elsevier, 2015)
      This paper presents a new sliding mesh technique for the computation of unsteady viscous flows in the presence of rotating bodies. The compressible Euler and incompressible Navier–Stokes equations are solved using a ...
    • Experimental study of aerated cavitation in a horizontal venturi nozzle 
      Article dans une revue avec comité de lecture
      TOMOV, Petar; VERTENOEUIL, P.; ccRAVELET, Florent; ccSARRAF, Christophe; ccBAKIR, Farid; ccKHELLADI, Sofiane (Elsevier, 2016)
      The injection of bubbles into an already cavitating flow is a way of influencing the typical cavitating behaviour. The present article deals with experiments on aerated and non-aerated cavitation in a transparent horizontal ...
    • Experimental investigation of an actively controlled automotive cooling fan using steady air injection in the leakage gap 
      Article dans une revue avec comité de lecture
      AZZAM, Tarik; PARIDAENS, Richard; OUALLI, Hamid; ccRAVELET, Florent; ccBAKIR, Farid; ccKHELLADI, Sofiane (SAGE Publications, 2017)
      In an axial fan, a leakage flow driven by a pressure gradient between the pressure side and the suction side occurs in the gap between the shroud and the casing. This leakage flow is in the opposite direction to the main ...
    • 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 ...
    • 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 ...
    • Smoothed Particle Hydrodynamics: A consistent model for interfacial multiphase fluid flow simulations 
      Article dans une revue avec comité de lecture
      KRIMI, Abdelkader; REZOUG, Mehdi; NOGUEIRA, Xesús; RAMÍREZ, Luis; ccDELIGANT, Michael; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, a consistent Smoothed Particle Hydrodynamics (SPH) model to deal with interfacial multiphase fluid flows simulation is proposed. A modification to the Continuum Stress Surface formulation (CSS) [1] to enhance ...
    • Coupling of inverse method and cuckoo search algorithm for multiobjective optimization design of an axial flow pump 
      Article dans une revue avec comité de lecture
      CHIKH, Mohamed Abdessamed Ait; BELAIDI, Idir; HAMRANI, Abderrachid; ccBAKIR, Farid; ccKHELLADI, Sofiane (SAGE Publications, 2019)
      This work describes the application of a multiobjective cuckoo search method for turbomachinery design optimization of an axial pump. Maximization of the total efficiency and minimization of the required net positive suction ...
