    • Global Instability in Shock Wave Laminar Boundary-Layer Interaction 
      Communication avec acte
      GUIHO, F.; ALIZARD, Frédéric; ccROBINET, Jean-Christophe (Springer, 2015)
      The linear global stability of an interaction between an oblique shock wave and a laminar boundary layer is carried out for various oblique shock angles. It is illustrated that such a flow acts as a noise amplifier. The ...
    • 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, ...
    • Lattice Boltzmann method for miscible gases: A forcing-term approach 
      Article dans une revue avec comité de lecture
      VIENNE, Lucien; MARIÉ, Simon; GRASSO, Francesco (American Physical Society (APS), 2019)
      A lattice Boltzmann method for miscible gases is presented. In this model, the standard lattice Boltzmann method is employed for each species composing the mixture. Diffusion interaction among species is taken into account ...
    • Simulation of Viscous Fingering Instability by the Lattice Boltzmann Method 
      Communication avec acte
      VIENNE, Lucien; MARIE, Simon; GRASSO, Francesco (American Institute of Aeronautics and Astronautics, 2019)
      The viscous fingering instability is successfully simulated within a lattice Boltzmann framework. Each species of the mixture is governed by its own kinetic equation and a force takes into account the diffusion between ...
    • Laminar supersonic sphere wake unstable bifurcations 
      Article dans une revue avec comité de lecture
      SANSICA, A.; OHMICHI, Y.; HASHIMOTO, A.; ccROBINET, Jean-Christophe (American Institute of Physics, 2020)
      The laminar sphere unstable bifurcations are sought at a Mach number of M∞ = 1.2. Global stability performed on steady axisymmetric base flows determines the regular bifurcation critical Reynolds number at Rereg cr = 650, ...
    • Performance assessment of a standard radial turbine as turbo expander for an adapted solar concentration ORC 
      Article dans une revue avec comité de lecture
      SAURET, Emilie; DANEL, Quentin; ccDELIGANT, Michael; ccBAKIR, Farid (Elsevier, 2020)
      Organic Rankine cycles are one of the available solutions for converting low grade heat source into electrical power. However the development of plants tends to be very expansive due to the specific design of the expander. ...
    • 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 ...
