• A simple embedded discrete fracture-matrix model for a coupled flow and transport problem in prous media 

      Odsæter, Lars Hov; Kvamsdal, Trond; Larson, Mats (Journal article; Peer reviewed, 2018)
      Accurate simulation of fluid flow and transport in fractured porous media is a key challenge in subsurface reservoir engineering. Due to the high ratio between its length and width, fractures can be modeled as lower ...
    • Liquid Hydrogen Spills on Water—Risk and Consequences of Rapid Phase Transition 

      Odsæter, Lars Hov; Skarsvåg, Hans Langva; Aursand, Eskil; Ustolin, Federico; Reigstad, Gunhild Allard; Paltrinieri, Nicola (Peer reviewed; Journal article, 2021)
      Liquid hydrogen (LH2 ) spills share many of the characteristics of liquefied natural gas (LNG) spills. LNG spills on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a ...
    • Postprocessing of non-conservative flux for compatibility with transport in heterogeneous media 

      Wheeler, Mary F.; Kvamsdal, Trond; Odsæter, Lars Hov; Larson, Mats (Journal article; Peer reviewed, 2016)
      A conservative flux postprocessing algorithm is presented for both steady-state and dynamic flow models. The postprocessed flux is shown to have the same convergence order as the original flux. An arbitrary flux approximation ...
    • Reservoir Simulation in Heterogeneous and Fractured Reservoirs 

      Odsæter, Lars Hov (Doctoral theses at NTNU;2018:165, Doctoral thesis, 2018)
      Summary of the thesis This thesis addresses simulation of flow and transport of fluids and fluid components in heterogeneous and fractured porous media. Reservoir simulation is a key component in several engineering ...
    • Risk and Consequences of Rapid Phase Transition for Liquid Hydrogen 

      Aursand, Eskil; Odsæter, Lars Hov; Skarsvåg, Hans Langva; Reigstad, Gunhild Allard; Ustolin, Federico; Paltrinieri, Nicola (Chapter, 2020)
      Safe handling of liquid hydrogen (LH2) has gained extra attention over the last years due to an increase in usage to mitigate climate changes. Rapid phase transition (RPT) is a potential safety concern when cryogens, like ...
    • Theories and Mechanism of Rapid Phase Transition 

      Ustolin, Federico; Odsæter, Lars Hov; Reigstad, Gunhild Allard; Skarsvåg, Hans Langva; Paltrinieri, Nicola (Peer reviewed; Journal article, 2020)
      Light hydrocarbons and hydrogen can replace high-alkane fuels with the benefit of reduced CO2 emissions. Their liquefaction to a cryogenic state is one of the most suitable solutions for storage and transport. An unexpected ...
