    • Global transition dynamics of flow in a lid-driven cubical cavity 
      Article dans une revue avec comité de lecture
      RANJAN, Rajesh; UNNIKRISHNAN, Sasidharan; GAITONDE, Datta; ccROBINET, Jean-Christophe (Springer Science and Business Media LLC, 2021)
      The dynamics of a fully three-dimensional lid-driven cubical cavity (3D-LDC) flow at several postcritical conditions, i.e., beyond the first bifurcation, are elucidated using both linear and nonlinear analyses. When the ...
    • Numerical investigation of three-dimensional partial cavitation in a Venturi geometry 
      Article dans une revue avec comité de lecture
      GOUIN, Camille; JUNQUEIRA-JUNIOR, Carlos; GONCALVES DA SILVA, Eric; ccROBINET, Jean-Christophe (AIP Publishing, 2021)
      Sheet cavitation appears in many hydraulic applications and can lead to technical issues. Some fundamental outcomes, such as, the complex topology of 3-dimensional cavitation pockets and their associated dynamics need to ...
    • Influence of freestream turbulence on the flow over a wall roughness 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; CHERUBINI, Stefania; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (American Physical Society (APS), 2021)
      The effect of freestream turbulence on the dynamics of an incompressible flow past a cylindrical roughness element in subcritical conditions (i.e., for Reynolds numbers below the onset of linear instability) has been ...
    • 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 ...
    • COMPUTATIONALLY INEXPENSIVE FREE VORTEX METHOD TO OBTAIN VORTEX CORE POSITION IN THE WAKE OF A HORIZONTAL AXIS WIND TURBINE 
      Article dans une revue avec comité de lecture
      MEGHLAOUI, Issam; DOBREV, Ivan; MASSOUH, Fawaz; BENRETEM, A. Ouahab; KHALFA, Dalila (Begell House, 2017)
      This work aims to develop a free wake model, allowing quick simulation of flow through a horizontal axis wind turbine. The rapidity of computation is particularly interesting when this aerodynamic model is integrated with ...
    • A Priori Tests of RANS Models for Turbulent Channel Flows of a Dense Gas 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer Verlag (Germany), 2018)
      Dense gas effects, encountered in many engineering applications, lead to unconventional variations of the thermodynamic and transport properties in the supersonic flow regime, which in turn are responsible for considerable ...
    • Adaptive filtering for the lattice Boltzmann method 
      Article dans une revue avec comité de lecture
      MARIÉ, Simon; ccGLOERFELT, Xavier (Elsevier, 2017)
      In this study, a new selective filtering technique is proposed for the Lattice Boltzmann Method. This technique is based on an adaptive implementation of the selective filter coefficient σ. The proposed model makes the ...
