    • Vortex Induced Vibration Analysis of a Cantilevered Hydrofoil by Laser Vibrometry and TR-PIV 
      Communication avec acte
      LEROY, Laure; ccBOT, Patrick (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
      GOULVEN, Thomas; HABERT, Benoît; ccBOT, Patrick (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; ccSAUX, 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 ...
    • Extraction de connaissances pour la description de l'environnement maritime côtier à partir de textes d'aide à la navigation 
      Communication avec acte
      LAMOTTE, Léa; ABADIE, Nathalie; ccSAUX, Eric; KERGOSIEN, Eric (RNTI, 2020-01-27)
      Les référentiels de données géoréférencées sont de plus en plus utilisés pour permettre l'annotation spatiale de documents textuels et ainsi faciliter l'accès à leur contenu, voire son analyse spatiale. En revanche, peu ...
    • Verification and validation for the cavitating flow around a NACA0015 hydrofoil 
      Communication avec acte
      PERALI, Paolo; LEROYER, Alban; VISONNEAU, Michel; ccHAUVILLE, Frederic (2019)
      When cavitation occurs around hydrofoils it is the cause of noise radiation, vibration and erosion. Consequently numerical cavitation models have been developped and tested over the last decades (Schnerr and Sauer [1]). ...
    • Turbulent flow around circular arcs 
      Article dans une revue avec comité de lecture
      SOUPPEZ, Jean-Baptiste R.G.; VIOLA, Ignazio Maria; ccBOT, Patrick (AIP Publishing, 2022)
      The flow around a circular arc is governed by the effect of the sharp leading edge and the arc’s curvature. There is a range of incidences where a leading-edge separation bubble (LESB) is formed on the convex side of the ...
