• A method for simulating two-phase pipe flow with real equations of state 

      Hammer, Morten; Morin, Alexandre (Journal article; Peer reviewed, 2014)
      Common two-fluid models for pipe flow assume local non-equilibrium regarding phase transfer. To solve the two-fluid models together with accurate equations of state for real fluids will in most cases require mechanical, ...
    • 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 (Peer reviewed; Journal article, 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 ...
    • CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods 

      Aursand, Eskil; Dørum, Cato; Hammer, Morten; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2014)
      One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ...
    • Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model 

      Aursand, Eskil; Dumoulin, Stephane; Hammer, Morten; Lange, Hans Iver; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Journal article; Peer reviewed, 2016)
      Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO2 is transported. To overcome this, a coupled fluid-structure ...
