    • Depressurization of CO2 in a pipe: Effect of initial state on non-equilibrium two-phase flow 

      Log, Alexandra Metallinou; Hammer, Morten; Deng, Han; Austegard, Anders; Hafner, Armin; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)
      It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ...

    • The effects of Stefan flow on the flow surrounding two closely spaced particles 

      Jayawickrama, Thamali R.; Chishty, Muhammad Aqib; Haugen, Nils Erland L; Bäbler, Matthâus Ulrich; Umeki, Kentaro (Peer reviewed; Journal article, 2023)
      The aim of the work was to study the effects of neighboring particles with uniform Stefan flow in particle–fluid flows. Particle-resolved numerical simulations were carried out for particles emitting a uniform Stefan flow ...

    • Experiments and modelling of choked flow of CO2 in orifices and nozzles 

      Hammer, Morten; Deng, Han; Austegard, Anders; Log, Alexandra Metallinou; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2022)
      In order to accelerate the deployment of capture and storage (CCS), engineers need experimentally validated models, among other things, to predict the mass flow rate in process equipment and flow restrictions like valves, ...

    • A flashing flow model for the rapid depressurization of CO2 in a pipe accounting for bubble nucleation and growth 

      Log, Alexandra Metallinou; Hammer, Morten; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)
      Flashing flow is encountered in many industrial systems involving nozzles, valves and decompression of vessels and pipes. In the context of CO2 capture and storage (CCS), the design of safe and efficient CO2 transportation ...

    • Influence of surfactants on the electrohydrodynamic stretching of water drops in oil 

      Ervik, Åsmund; Penne, Torstein Eidsnes; Hellesø, Svein Magne; Munkejord, Svend Tollak; Müller, Bernhard (Journal article; Peer reviewed, 2017)
      In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly ...

    • Upward and downward two-phase flow of in a pipe: Comparison between experimental data and model predictions 

      Hammer, Morten; Deng, Han; Liu, Lan; Langsholt, Morten Chr.; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2021)
      In order to deploy capture and storage (CCS) systems to mitigate climate change, it is crucial to develop reliable models for design and operational considerations. A key element of the system is the interface between ...
