    • An experimental blade-controlled platform for the design of smart cross-flow propeller 
      Article dans une revue avec comité de lecture
      FASSE, Guillaume; BECKER, Florent; ccHAUVILLE, Frederic; ccASTOLFI, Jacques Andre; GERMAIN, Grégory (Elsevier BV, 2022-04)
      As an academic platform, the French Naval Academy Research Institute (IRENav) developed a large-scale experimental cycloidal propeller (800 kg, 0.4 m radius) with the aim of running diverse pitch motions to evaluate ...
    • 6DOF behavior of an offshore racing trimaran in an unsteady environment 
      Communication avec acte
      KERDRAON, Paul; HOREL, Boris; ccBOT, Patrick; LETOURNEUR, Adrien; LE TOUZÉ, David (SNAME, 2019-03)
      While in recent years the use of hydrofoils has experienced a substantial growth, traditional design tools such as Velocity Prediction Programs (VPP) have proven inadequate to help architects and engineers with performance ...
    • Surrogates and Classification approaches for Efficient Global Optimization (EGO) with Inequality Constraints 
      Communication avec acte
      SACHER, Matthieu; DUVIGNEAU, Régis; LE MAITRE, Olivier; DURAND, Mathieu; BERRINI, Elisa; ccHAUVILLE, Frederic; ccASTOLFI, Jacques Andre (2017-05)
      In this work, we compare the use of Gaussian Process (GP) models for the constraints [Schonlau 1997] with a classification approach relying on a Least-Squares Support Vector Machine (LS-SVM) [Suykens and Vandewalle 1999]. ...
    • Vortex Induced Vibration Analysis of a Cantilevered Hydrofoil by Laser Vibrometry and TR-PIV 
      Communication avec acte
      ccASTOLFI, Jacques Andre; ccBOT, Patrick; LEROY, Laure (X. Amandolese & P. Hémon, 2020-05)
      The structural response of a steel cantilevered hydrofoil is analyzed through an experiment carried out in a hydrodynamic tunnel for Reynolds numbers ranging from 2 105 to 8:25 105. The hydrofoil is set at a 17 angle to ...
    • A New Sensor to Characterize Flow Separation on a Hydrofoil 
      Communication avec acte
      VOISIN, Dimitri; SOULIER, Antoine; ccBOT, Patrick (I. M. Viola & F. Brennan (MARINE 2021), 2021)
      The performance of lifting bodies such as hydrofoils is determined by the flow state and particular attention should be paid to flow separation, as this greatly affects the generated lift and drag. Sailors are used to look ...
    • Flow field and forces on a highly curved plate 
      Communication avec acte
      THOMAS, Goulven; ccBOT, Patrick; HABERT, Benoît (ISPIV, 2019-07)
      While both slender wings and bluff bodies are the usual focus of classical fluid dynamics, the behavior of a high-lift not-so-slender body remains somehow original. This work presents an experimental investigation of a ...
    • Approche ontologique pour la modélisation de carte contextuelle 
      Communication sans acte
      KOTEICH, Bilal; SAUX, Eric; GRANCHER, Arnaud (2019-11)
      This paper first presents a state of the art of context modeling approaches in an information system. We then propose an approach based on a spatial-temporal ontology to automate the data selection step in the process of ...
