    • Sparse Bayesian Learning of Explicit Algebraic Reynolds-Stress models for turbulent separated flows 
      Article dans une revue avec comité de lecture
      CHERROUD, Soufiane; MERLE, Xavier; ccCINNELLA, Paola; ccGLOERFELT, Xavier (Elsevier BV, 2022-12)
      A novel Sparse Bayesian Learning (SBL) framework is introduced for generating parsimonious stochastic algebraic stress closures for the Reynolds-Averaged Navier–Stokes (RANS) equations from high-fidelity data. The models ...
    • Bayesian model-scenario averaged predictions of compressor cascade flows under uncertain turbulence models 
      Article dans une revue avec comité de lecture
      ccDE ZORDO-BANLIAT, Maximilien; MERLE, Xavier; ccDERGHAM, Grégory; ccCINNELLA, Paola (Elsevier BV, 2020-04)
      The Reynolds-Averaged Navier-Stokes (RANS) equations represent the computational workhorse for engineering design, despite their numerous flaws. Improving and quantifying the uncertainties associated with RANS models is ...
    • CFD-driven symbolic identification of algebraic Reynolds-stress models 
      Article dans une revue avec comité de lecture
      ccBEN HASSAN SAIDI, Ismaïl; ccSCHMELZER, Martin; ccCINNELLA, Paola; GRASSO, Francesco (Elsevier Inc., 2022-02)
      Reynolds-stress models (EARSM) from high-fidelity data is developed building on the frozen-training SpaRTA algorithm of [1]. Corrections for the Reynolds stress tensor and the production of transported turbulent quantities ...
    • Quantitative analysis of lower limb and pelvic deformities in children with X-linked hypophosphatemic rickets 
      Article dans une revue avec comité de lecture
      ccBONNET-LEBRUN, Aurore; ccLINGLART, Agnès; DE TIENDA, Marine; OUCHRIF, Younes; BERKENOU, Jugurtha; ccASSI, Ayman; WICART, Philippe; ccSKALLI, Wafa (Elsevier BV, 2021-12)
      Introduction X-linked hypophosphatemia (XLH) rickets mainly causes leg deformities in children that can get worse as they grow. We hypothesized that quantifying the bone parameters will help to document and monitor these ...
    • Effect of postural alignment alteration with age on vertebral strength 
      Article dans une revue avec comité de lecture
      ccHEIDSIECK, Cécile; ccGAJNY, Laurent; ccTRAVERT, Christophe; ccLAZENNEC, Jean Yves; ccSKALLI, Wafa (Springer Science and Business Media LLC, 2021-09)
      Purpose. The purpose of this study was to analyze the impact of postural alignment changes with age on vertebral strength using finite element analysis and barycentremetry. Methods. A total of 117 subjects from 20 to 83 ...
    • DNS of turbulent flows of dense gases 
      Article dans une revue avec comité de lecture
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier; GRASSO, Francesco (IOP Publishing, 2017-04)
      The influence of dense gas effects on compressible turbulence is investigated by means of numerical simulations of the decay of compressible homogeneous isotropic turbulence (CHIT) and of supersonic turbulent flows through ...
    • Analysis of Dense Gas Effects in Compressible Turbulent Channel Flows 
      Communication avec acte
      ccSCIACOVELLI, Luca; ccCINNELLA, Paola; ccGLOERFELT, Xavier (Springer International Publishing, 2019-02-02)
      In this work we investigate the influence of dense gas effects on compressible wall-bounded turbulence. Turbulent flows of dense gases represent a research field of great importance for a wide range of applications in ...
