    • 3D NUMERISK MODELLERING AV DELER AV VANNVEGEN TIL TONSTAD KRAFTVERK 

      Brevik, Oddmund (Master thesis, 2013)
      Denne masteroppgåva handlar om bruk av numerisk modellering («Computational Fluid Dynamics», CFD) i høve til sandfang 3 ved Tonstad kraftverk. Oppgåva tek utgangspunkt i geometri og feltmålingar frå sandfanget. For å ...

    • Calibration of Horizontal Acoustic Doppler Current Profiler by three dimensional CFD simulations 

      Bråtveit, Kari; Olsen, Nils Reidar Bøe (Journal article; Peer reviewed, 2015)
      This study presents a calibration method of horizontal acoustic Doppler current profilers (H-ADCP), based on 3D Computational Fluid Dynamics (CFD) simulations. Rigidly mounted H-ACCPs are currently used to continuously ...
