      Variational optimization has been recently applied to nonlinear systems with many degrees of freedom such as shear flows undergoing transition to turbulence. This technique has unveiled powerful energy growth mechanisms ...

      Superhydrophobic surfaces dramatically reduce the skin friction of overlying liquid flows, providing a lubricating layer of gas bubbles trapped within their surface nano-sculptures. Under wetting-stable conditions, different ...

      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 ...

      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 ...

      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 ...

      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 ...

      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 ...
