    • CFD modelling of mixing in a small-scale UASB biogas reactor 

      Midtbø, Kristine (Master thesis, 2022)
      Denne avhandlingen tar for seg hvordan innkommende substrat mikses i Telemarksreaktoren (TR) ved å bruke numerisk fluiddynamikk (CFD) til å simulere forskjellige strømningsmønstre i reaktoren slik at miksingen kan forbedres. ...

    • Modelling of gas explosions 

      Vågsæther, Knut (Doktoravhandlinger ved NTNU, 1503-8181; 2010:221, Doctoral thesis, 2010)
      The content of this thesis is a study of gas explosions in complex geometries and presentation and validation of a method for simulating flame acceleration and deflagration to detonation transition. The thesis includes a ...

    • Pressure wave propagation in Managed Pressure Drilling- model comparison with real life data 

      Berg, Christian; Stakvik, Jon Åge; Lie, Bernt; Vågsæther, Knut; Kaasa, Glenn-Ole (Journal article; Peer reviewed, 2019)
      Drilling for oil and gas is a complex process, involving pumping of fluid through kilometers of pipes. Even though the drilling fluid has a high speed of sound (˜1000 m/s), the large lengths involved make pressure wave ...
