    • Transient growth in the flow past a three-dimensional smooth roughness element 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; DE TULLIO, Marco; DE PALMA, Pietro; PASCAZIO, Giuseppe (Cambridge University Press (CUP), 2013)
      This work provides a global optimization analysis, looking for perturbations inducing the largest energy growth at a finite time in a boundary-layer flow in the presence of smooth three-dimensional roughness elements. ...
    • Investigation of the roughness-induced transition: global stability analyses and direct numerical simulations 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; LERICHE, Emmanuel; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2014)
      The linear global instability and resulting transition to turbulence induced by an isolated cylindrical roughness element of height h and diameter d immersed within an incompressible boundary layer flow along a flat plate ...
    • Fast acoustic streaming in standing waves : Generation of an additional outer streaming cell 
      Article dans une revue avec comité de lecture
      REYT, Ida; BAILLIET, Hélène; MOREAU, Solène; VALIERE, Jean-Christophe; BALTEAN-CARLÈS, Diana; WEISMAN, Catherine; ccDARU, Virginie (Acoustical Society of America, 2013)
      Rayleigh streaming in a cylindrical acoustic standing waveguide is studied both experimentally and numerically for nonlinear Reynolds numbers from 1 to 30. Streaming velocity is measured by means of laser Doppler velocimetry ...
    • Experimental and numerical study of flow around a wind turbine rotor 
      Article dans une revue avec comité de lecture
      DOBREV, Ivan; MASSOUH, Fawaz; MEMON, Asif (InderScience, 2013)
      An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of ...
    • Experimental study of yawed inflow around wind turbine rotor 
      Article dans une revue avec comité de lecture
      NOURA, Belkheir; DOBREV, Ivan; DIZENE, Rabah; MASSOUH, Fawaz; ccKHELLADI, Sofiane (SAGE Publications, 2012)
      In this article, we present an experimental study in a wind tunnel of a three-bladed, Rutland 503 model, horizontal axis yawed wind turbine. Power measurement and an exploration downstream wake of the turbine using particle ...
    • Numerical Study of the Effect of Freestream Turbulence on by-pass Transition in a Boundary Layer 
      Article dans une revue avec comité de lecture
      CHERUBINI, Stefania; DE PALMA, Pietro; ccROBINET, Jean-Christophe (Elsevier, 2014)
      We use direct numerical simulations in the presence of free-stream turbulence having different values of intensity, T u, and integral length scale, L, in order to determine which kind of structures are involved in the path ...
    • Bayesian quantification of thermodynamic uncertainties in dense gas flows 
      Article dans une revue avec comité de lecture
      MERLE, Xavier; CINNELLA, Paola (Elsevier, 2014)
      A Bayesian inference methodology is developed for calibrating complex equations of state used in numerical fluid flow solvers. Precisely, the input parameters of three equations of state commonly used for modeling the ...
