    • Aeroacoustic Study of the Interaction of a Rotating Blade with a Batchelor Vortex 
      Article dans une revue avec comité de lecture
      ZEHNER, Paul; FALISSARD, Fabrice; ccGLOERFELT, Xavier (American Institute of Aeronautics and Astronautics, 2018)
      The aeroacoustic response of the orthogonal interaction of a rotating blade with an isolated Batchelor vortex is studied by means of numerical simulation. The relative influence of the vortex tangential and axial velocity ...
    • Multiphase smoothed particle hydrodynamics approach for modeling soil–water interactions 
      Article dans une revue avec comité de lecture
      KRIMI, Abdelkader; NOGUEIRA, Xesús; ATA, Riadh; REZOUG, Mehdi; ccDELIGANT, Michael; ccKHELLADI, Sofiane (Elsevier, 2018)
      In this work, a weakly compressible smoothed particle hydrodynamics (WCSPH) multiphase model is developed. The model is able to deal with soil-water interactions coupled in a strong and natural form. A Regularized Bingham ...
    • 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 ...
    • Implementation of surface tension force in fluid flow during reactive rotational molding 
      Article dans une revue avec comité de lecture
      HAMIDI, A.; ILLOUL, A.; SHIRINBAYAN, Mohammadali; ccTCHARKHTCHI, Abbas; ccBAKIR, Farid; ccKHELLADI, Sofiane (Springer Verlag, 2015)
      During Reactive Rotational Molding (RRM), it is very important to predict the fluid flow in order to obtain the piece with homogeneous shape and high quality. This prediction may be possible by simulation the fluid flow ...
    • Modal and non-modal linear stability of Poiseuille flow through a channel with a porous substrate 
      Article dans une revue avec comité de lecture
      GHOSH, Souvik; BREUGEM, Wim-Paul; BRANDT, Luca; ccLOISEAU, Jean-Christophe (Elsevier, 2019)
      We present modal and non-modal linear stability analyses of Poiseuille flow through a plane channel with a porous substrate modeled using the Volume Averaged Navier–Stokes (VANS) equations. Modal stability analysis shows ...
    • Numerical investigation of the interaction between laminar to turbulent transition and the wake of an airfoil 
      Article dans une revue avec comité de lecture
      DUCOIN, A.; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Elsevier, 2016)
      The objective of this work is to investigate numerically the different physical mechanisms of the transition to turbulence of a separated boundary-layer flow over an airfoil at low angle of attack. In this study, the ...
