    • 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 ...

    • Enhanced Spin Conductance of a Thin-Film Insulating Antiferromagnet 

      Bender, Scott A.; Skarsvåg, Hans Langva; Brataas, Arne; Duine, R A (Journal article; Peer reviewed, 2017)
      We investigate spin transport by thermally excited spin waves in an antiferromagnetic insulator. Starting from a stochastic Landau-Lifshitz-Gilbert phenomenology, we obtain the out-of-equilibrium spin-wave properties. In ...

    • Experimental Investigation into the Consequences of Release of Liquified Hydrogen onto and under Water 

      van Wingerden, Kees; Kluge, Martin; Habib, Abdel Karim; Skarsvåg, Hans Langva; Ustolin, Federico; Paltrinieri, Nicola; Odsæter, Lars Hov (Peer reviewed; Journal article, 2022)
      Large-scale experiments have been performed to investigate the possible consequences of realistic amounts of liquified hydrogen (LH2) encountering water. The experiments aimed at simulating an accidental release of LH2 ...

    • 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 ...

    • Normal and superfluid spin dynamics in magnetic insulator heterostructures 

      Skarsvåg, Hans Langva (Doctoral theses at NTNU;2016:334, Doctoral thesis, 2016)
      Summary of thesis: Normal and superfluid spin dynamics in magnetic insulator heterostructures In this thesis, the results of six research papers on spintronics-related effects are presented. The main focus is on ...

    • 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 ...

    • Spin Superfluidity in Biaxial Antiferromagnetic Insulators 

      Qaiumzadeh, Alireza; Skarsvåg, Hans Langva; Holmqvist, Cecilia; Brataas, Arne (Journal article; Peer reviewed, 2017)
      Antiferromagnets may exhibit spin superfluidity since the dipole interaction is weak. We seek to establish that this phenomenon occurs in insulators such as NiO, which is a good spin conductor according to previous studies. ...

    • Spin-transfer antiferromagnetic resonance 

      Johansen, Øyvind; Skarsvåg, Hans Langva; Brataas, Arne (Journal article; Peer reviewed, 2018)
      Currents can induce spin excitations in antiferromagnets, even when they are insulating. We investigate how spin transfer can cause antiferromagnetic resonance in bilayers and trilayers that consist of one antiferromagnetic ...

    • 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 ...

    • Towards an engineering tool for the prediction of running ductile fractures in CO2 pipelines 

      Skarsvåg, Hans Langva; Hammer, Morten; Munkejord, Svend Tollak; Log, Alexandra Metallinou; Dumoulin, Stephane; Gruben, Gaute (Peer reviewed; Journal article, 2023)
      A prerequisite for the deployment of CO2 capture and storage (CCS) is to establish a large network of high-pressure transport pipelines. It is then vital to assess new and existing pipeline designs for running ductile ...
