• 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 Investigation of Tucked Positions in Alpine Skiing 

      Elfmark, Ola; Giljarhus, Knut Erik Teigen; Liland, Fredrik Fang; Oggiano, Luca; Reid, Robert (Peer reviewed; Journal article, 2021)
      The purpose of this investigation was to examine the aerodynamics of tucked positions in competitive alpine skiing. To further our understanding of how a skier’s position affects the air flow and the resulting aerodynamic ...
    • An Empirical Model of Aerodynamic Drag in Alpine Skiing 

      Elfmark, Ola; Bardal, Lars Morten (Journal article; Peer reviewed, 2018)
      This paper describes an empirical model of aerodynamic drag for a range of body positions commonly used in alpine skiing. In order to calculate the drag coefficient (CD), a method for calculating the frontal area of an ...
    • Blockage Correction and Reynolds Number Dependency of an Alpine Skier: A Comparison Between Two Closed-Section Wind Tunnels. 

      Elfmark, Ola; Reid, Robert Cortas; Bardal, Lars Morten (Peer reviewed; Journal article, 2020)
      The purpose of this study was to investigate the impact of blockage effect and Reynolds Number dependency by comparing measurements of an alpine skier in standardized positions between two wind tunnels with varying blockage ...
    • Modelling of Aerodynamic Drag in Alpine Skiing 

      Elfmark, Ola (Master thesis, 2017)
      Most of the breaking force in the speed disciplines in alpine skiing is caused by the aerodynamic drag, and a better knowledge of the drag force is therefore desirable to gain time in races. In this study a complete database ...
    • The Effect of Arm Positions on Flow Around an Alpine Skier 

      Støre, Jonas Østergaard (Master thesis, 2021)
      There have been limited research increasing knowledge of flow around an alpine skier, and the effect of different arm positions. In this study, a wind tunnel experiment were conducted testing five different arm positions ...
