    • Data-Free and Data-Driven RANS Predictions with Quantified Uncertainty 
      Article dans une revue avec comité de lecture
      EDELING, Wouter Nico; IACCARINO, Gianluca; CINNELLA, Paola (Springer Verlag (Germany), 2017)
      For the purpose of estimating the epistemic model-form uncertainty in Reynolds-Averaged Navier-Stokes closures, we propose two transport equations to locally perturb the Reynolds stress tensor of a given baseline eddy-viscosity ...
    • Inertial effects on acoustic Rayleigh streaming flow: Transient and established regimes 
      Article dans une revue avec comité de lecture
      WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; REYT, Ida; BAILLIET, Hélène; ccDARU, Virginie (Elsevier, 2017)
      The effect of inertia on Rayleigh streaming generated inside a cylindrical resonator where a mono-frequency standing wave is imposed, is investigated numerically and experimentally. To this effect, time evolutions of ...
    • Acoustic and streaming velocity components in a resonant waveguide at high acoustic levels 
      Article dans une revue avec comité de lecture
      REYT, Ida; BAILLIET, Hélène; WEISMAN, Catherine; BALTEAN-CARLÈS, Diana; ccDARU, Virginie (Acoustical Society of America, 2017)
      Rayleigh streaming is a steady flow generated by the interaction between an acoustic wave and a solid wall, generally assumed to be second order in a Mach number expansion. Acoustic streaming is well known in the case of ...
    • Optimal perturbation for two-dimensional vortex systems: route to non-axisymmetric state 
      Article dans une revue avec comité de lecture
      NAVROSE; JOHNSON, Author H. G.; BRION, Véronique; JACQUIN, Laurent; ccROBINET, Jean-Christophe (Cambridge University Press (CUP), 2018)
      We investigate perturbations that maximize the gain of disturbance energy in a two-dimensional isolated vortex and a counter-rotating vortex pair. The optimization is carried out using the method of Lagrange multipliers. ...
    • Experimental investigation on the effect of load distribution on the performances of a counter-rotating axial-flow fan 
      Article dans une revue avec comité de lecture
      WANG, Juan; ccRAVELET, Florent; ccSARRAF, Christophe; ccBAKIR, Farid (Elsevier, 2018)
      In the design procedure of a counter-rotating axial-flow stage, parameters such as the angular velocity ratio and the repartition of the work performed by each rotors are to be chosen. In the present Article, three ...
    • Successive bifurcations in a fully three-dimensional open cavity flow 
      Article dans une revue avec comité de lecture
      PICELLA, Francesco; LUSSEYRAN, F; CHERUBINI, Stefania; PASTUR, L; ccROBINET, Jean-Christophe; ccLOISEAU, Jean-Christophe (Cambridge University Press (CUP), 2018)
      The transition to unsteadiness of a three-dimensional open cavity flow is investigated using the joint application of direct numerical simulations and fully three-dimensional linear stability analyses, providing a clear ...
    • Thermal aging kinetic and effects on mechanical behavior of fully recycled composite based on polypropylene/polyethylene blend 
      Article dans une revue avec comité de lecture
      TAMBOURA, Sahbi; BENDALY, Hachmi; FITOUSSI, Jean Paul; MEFTAH, Hicham; ccTCHARKHTCHI, Abbas (Wiley, 2018)
      The effect of thermal oxidation of a fully recycled carbon fibers reinforced stabilized polypropylene/polyethylene blend on the mechanical properties has been studied at 120, 130 and 140 °C. In a first step, several analyses ...
