    • Dense-gas effects on compressible boundary-layer stability 
      Article dans une revue avec comité de lecture
      CINNELLA, Paola; GRASSO, Francesco; ccROBINET, Jean-Christophe; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Cambridge University Press (CUP), 2020)
      A study of dense-gas effects on the stability of compressible boundary-layer flows is conducted. From the laminar similarity solution, the temperature variations are small due to the high specific heat of dense gases, ...
    • Space–time dynamics of optimal wavepackets for streaks in a channel entrance flow 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; CADIOU, A.; LE PENVEN, L.; DI PIERRO, B.; BUFFAT, M. (Cambridge University Press (CUP), 2018)
      The laminar–turbulent transition of a plane channel entrance flow is revisited using global linear optimization analyses and direct numerical simulations. The investigated case corresponds to uniform upstream velocity ...
    • Development of a third-order accurate vorticity confinement scheme 
      Article dans une revue avec comité de lecture
      COSTES, M.; PETROPOULOS, I.; ccCINNELLA, Paola (ELSEVIER, 2016)
      A new 3rd-order Vorticity Confinement scheme is presented as an extension of the original VC2 scheme developed by Steinhofffor the resolution of the fluid dynamic equations. The theoretical developments are explained, and ...
    • Sensitivity analysis of optimal transient growth for turbulent boundary layers 
      Article dans une revue avec comité de lecture
      ALIZARD, Frédéric; FILLIARD, Guillaume; ccROBINET, Jean-Christophe (Elsevier, 2015)
      Structural approaches based on modal decomposition of the flow dynamics have gained acceptance for a wide variety of turbulent shear flows. In this context, a singular value decomposition associated with a governing operator, ...
    • An a posteriori-implicit turbulent model with automatic dissipation adjustment for Large Eddy Simulation of compressible flows 
      Article dans une revue avec comité de lecture
      NOGUEIRA, Xesús; RAMÍREZ, Luis; FERNÁNDEZ-FIDALGO, Javier; ccDELIGANT, Michael; ccKHELLADI, Sofiane; CHASSAING, Jean-Camille; NAVARRINA, Fermín (ELSEVIER, 2020)
      In this work we present an a posteriori high-order finite volume scheme for the computation of compressible turbulent flows. An automatic dissipation adjustment (ADA) method is combined with the a posteriori paradigm, in ...
    • Roughness-induced transition by quasi-resonance of a varicose global mode 
      Article dans une revue avec comité de lecture
      BUCCI, Michele Alessandro; PUCKERT, Dominik K.; ANDRIANO, Cesare; CHERUBINI, Stefania; RIST, Ulrich; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2017)
      The onset of unsteadiness in a boundary-layer flow past a cylindrical roughness element is investigated for three flow configurations at subcritical Reynolds numbers, both experimentally and numerically. On the one hand, ...
    • 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 ...
