    • Development of an Experimental Blade-controlled Cycloidal Propeller 
      Communication avec acte
      FASSE, Guillaume; GERMAIN, Gregory; BECKER, Florent; ccHAUVILLE, Frederic (AFM, 2019)
      As an interesting naval propulsion system, this paper presents the development of an experimental cycloidal propeller. Cross-flow propellers are characterized by the rotation of several blades around a vertical axis ...
    • Turbulent flow around circular arcs 
      Article dans une revue avec comité de lecture
      SOUPPEZ, Jean-Baptiste R.G.; ccBOT, Patrick; VIOLA, Ignazio Maria (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 ...
    • Performance Improvement of a Darrieus Tidal Turbine with Active Variable Pitch 
      Article dans une revue avec comité de lecture
      DELAFIN, Pierre-Luc; DENISET, François; ccASTOLFI, Jacques Andre; ccHAUVILLE, Frederic (MDPI AG, 2021)
      Vertical axis turbines, also called Darrieus turbines, present interesting characteristics for offshore wind and tidal applications but suffer from vibrations and a lower efficiency than the more conventional horizontal ...
    • Verification and validation for the cavitating flow around a NACA0015 hydrofoil 
      Communication avec acte
      PERALI, Paolo; ccHAUVILLE, Frederic; LEROYER, Alban; VISONNEAU, Michel (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]). ...
    • On Integrating Size and Shape Distributions into a Spatio-Temporal Information Entropy Framework 
      Article dans une revue avec comité de lecture
      LEIBOVICI, Didier; CLARAMUNT, Christophe (MDPI, 2019)
      Understanding the structuration of spatio-temporal information is a common endeavour to many disciplines and application domains, e.g., geography, ecology, urban planning, epidemiology. Revealing the processes involved, ...
    • Visualizing urban sprawl effects of a Tunisian city: a new urban spatial configuration of Monastir 
      Article dans une revue avec comité de lecture
      REJEB BOUZGARROU, Asma; REJEB, Hichem; CLARAMUNT, Christophe (Taylor & Francis, 2019)
      The purpose of this research is to study the dynamics associated with the physical transformations of the Tunisian city of Monastir between 1956 and 2013. Beyond the description and classification of urban forms of three ...
    • Socio-spatial influence maximization in location-based social networks 
      Article dans une revue avec comité de lecture
      HOSSEINPOOR, Mohammad; MALEK, Mohammad Reza; CLARAMUNT, Christophe (Elsevier, 2019)
      Identifying influential nodes in social networks is a key issue in many domains such as sociology, economy, biology, and marketing. A common objective when studying such networks is to find the minimum number of nodes with ...
