    • On the Effect of the Leading-Edge Separation Bubble on the Aerodynamics of Spinnakers 
      Communication avec acte
      SOUPPEZ, Jean-Baptiste R.G.; ccBOT, Patrick; VIOLA, Ignazio Maria (RINA NZ, 2021-03)
      The spinnaker is the most powerful and one of the most used sails both in racing and cruising - yet its complex aerodynamics governed by flow separation is still not fully understood. While the flow around a spinnaker is ...
    • Thermochemical non-equilibrium effects in turbulent hypersonic boundary layers 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINNELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (2022-04-28)
      A hypersonic, spatially evolving turbulent boundary layer at Mach 12.48 with a cooled wall is analysed by means of direct numerical simulations. At the selected conditions, massive kinetic-to-internal energy conversion ...
    • Cycloidal Dynamic Propulsion or Positioning System For a Ship 
      Brevet
      DAMAY, Thomas; ccHAUVILLE, Frederic; ccASTOLFI, Jacques Andre (Patent Application Publication, 2022-03-03)
      A cycloidal dynamic propulsion or positioning system for a ship in water that exhibits a direction of flow, including a frame, a rotor mounted to be movable in rotation on the frame about a main axis at right angles to the ...
    • Assessment of a high-order shock-capturing central-difference scheme for hypersonic turbulent flow simulations 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (Elsevier, 2021-11)
      High-speed turbulent flows are encountered in most space-related applications (including exploration, tourism and defense fields) and represent a subject of growing interest in the last decades. A major challenge in ...
    • Finite-rate chemistry effects in turbulent hypersonic boundary layers: A direct numerical simulation study 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINELLA, Paola; GIUSEPPE, Pascazio; ccSCIACOVELLI, Luca (American Physical Society, 2021-05)
      The influence of high-enthalpy effects on hypersonic turbulent boundary layers is investigated by means of direct numerical simulations (DNS). A quasiadiabatic flat-plate air flow at free-stream Mach number equal to 10 is ...
    • Numerical Investigation of High‑Speed Turbulent Boundary Layers of Dense Gases 
      Article dans une revue avec comité de lecture
      PASSIATORE, Donatella; CINNELLA, Paola; GRASSO, Francesco; ccSCIACOVELLI, Luca; ccGLOERFELT, Xavier (Springer, 2020-03)
      High-speed turbulent boundary layers of a dense gas (PP11) and a perfect gas (air) over flat plates are investigated by means of direct numerical simulations and large eddy simulations. The thermodynamic conditions of the ...
    • A Non-Nested Infilling Strategy for Multi-Fidelity based Efficient Global Optimization 
      Article dans une revue avec comité de lecture
      SACHER, Matthieu; LE MAITRE, Olivier; DUVIGNEAU, Régis; ccHAUVILLE, Frederic; DURAND, Mathieu; LOTHODE, Corentin (Begell, 2021)
      Efficient global optimization (EGO) has become a standard approach for the global optimization of complex systems with high computational costs. EGO uses a training set of objective function values computed at selected ...
