    • A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transitions in LNG spills 

      Lervåg, Karl Yngve; Skarsvåg, Hans Langva; Aursand, Eskil; Ouassou, Jabir Ali; Hammer, Morten; Reigstad, Gunhild Allard; Ervik, Åsmund; Fyhn, Eirik Holm; Gjennestad, Magnus Aashammer; Aursand, Peder; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2020)
      Transport of liquefied natural gas (LNG) by ship occurs globally on a massive scale. The large temperature difference between LNG and water means LNG will boil violently if spilled onto water. This may cause a physical ...

    • Mathematical Modelling of Fluid Flows in Pipe Networks 

      Reigstad, Gunhild Allard (Doktoravhandlinger ved NTNU, 1503-8181; 2014:120, Doctoral thesis, 2014)
      The mathematical description of splitting and merging of flows is an important part of a detailed heat exchanger simulation model suitable for studying dynamic and static flow instabilities. This thesis considers one such ...

    • Pipe Networks: Coupling Constants in a Junction for the Isentropic Euler Equations 

      Morin, Alexandre; Reigstad, Gunhild Allard (Journal article; Peer reviewed, 2015)
      The modelling of junctions in pipe networks with subsonic flows is discussed, where pipes are described by one-dimensional, single-phase isentropic flow models. We first study the Riemann problem in a pipe to understand ...
