    • Aerodynamic Interaction between Two Speed Skaters Measured in a Closed Wind Tunnel 

      Elfmark, Ola; Bardal, Lars Morten; Oggiano, Luca; Myklebust, Håvard (Journal article, 2019)
      Team pursuit is a relatively new event in international long track speed skating. For a single speed skater the aerodynamic drag will account for up to 80% of the braking force, thus reducing the drag can greatly improve ...

    • Aerodynamic properties of textiles 

      Bardal, Lars Morten (Master thesis, 2010)
      The aerodynamic drag force acting on a circular cylinder clad with knitted wool and polyester textiles has been investigated in wind tunnel experiments in this study. Particle image velocimetry (PIV) was utilized to determine ...

    • Drag reduction and aerodynamic performances in Olympic sports 

      Oggiano, Luca (Doktoravhandlinger ved NTNU, 1503-8181; 2010:118, Doctoral thesis, 2010)
      In sports where high speed is involved, races are often won by milliseconds. Any advantage can then be important in order to reach the success. The drag acting on the athletes is often the highest force that the athletes ...

    • Influence of Fabric Structural Attributes on Their Aerodynamic Behavior 

      Bardal, Lars Morten; Oggiano, Luca (Journal article; Peer reviewed, 2013)
      The aerodynamic properties of 15 knitted fabrics of varying cover factor, yarn, and fiber compositions were investigated for their aerodynamic properties on circular cylinders in a wind tunnel. Measurements of the drag ...

    • The significant impact of ribs and small-scale roughness on cylinder drag crisis 

      Skeide, Arne Kilvik; Bardal, Lars Morten; Oggiano, Luca; Hearst, R. Jason (Peer reviewed; Journal article, 2020)
      The impact of flow-normal ribs and small-scale surface roughness on the drag and vortex shedding of a circular cylinder was investigated. Three rib heights, four relative rib spacings and three different forms of microroughness ...

    • Signifikant Reduksjon i Luftmotstanden på en Sylinder ved bruk av Striper og Tekstiler 

      Skeide, Arne Kilvik (Master thesis, 2019)
      Effekten av striper og små-skala overflateruhet på luftmotstanden og virvelavløsningen til en sirkulær sylinder, har blitt undersøkt. En sylinder ble dekket av et 'tekstil' bestående av halvsirkulære striper liggende ...

    • Validation of the real-time-response ProCap measurement system for full field wake scans behind a yawed model-scale wind turbine 

      Bartl, Jan Michael Simon; Müller, Andreas; Landolt, Andrin; Mühle, Franz Volker; Vatn, Mari; Oggiano, Luca; Sætran, Lars Roar (Journal article; Peer reviewed, 2018)
      For an accurate prediction of the complex flow conditions in wind farms, model scale wake flow measurements represent important references in well-defined boundary conditions. State-of-the art flow measurement techniques ...

    • Wake flow and aerodynamic performance of time trial helmets 

      Liland, Fredrik Fang (Master thesis, 2019)
      Luftmotstand er den viktigste motstandskraften i sykkelkonkurranser. For å forbedre den aerodynamiske ytelsen blir det brukt tempohjelmer som er spesielt designet for å redusere luftmotstanden. Tempohjelmene som er ...
