    • CO2 pipeline integrity: A new evaluation methodology 

      Berstad, Torodd; Dørum, Cato; Jakobsen, Jana Poplsteinova; Kragset, Steinar; Li, Hailong; Lund, Halvor; Morin, Alexandre; Munkejord, Svend Tollak; Mølnvik, Mona Jacobsen; Nordhagen, Håkon Ottar; Østby, Erling (Journal article; Peer reviewed, 2011)
      A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ...

    • Phase transitions in effective lattice models for strongly correlated systems 

      Kragset, Steinar (Doktoravhandlinger ved NTNU, 1503-8181; 2006:174, Doctoral thesis, 2006)
      In three research articles we have studied the critical properties of effective lattice models for strongly correlated electron systems by Monte Carlo simulations. A similar model is used in a fourth article for investigating ...

    • Pipeline flow modelling with source terms due to leakage: The straw method 

      Morin, Alexandre; Kragset, Steinar; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2012)
      A numerical method for calculating the leakage flow rate through a crack in a pressurized pipeline is presented. Calculations of the flow inside, and leakage from, a pipeline with a running crack are performed. For the ...
