• Thermodynamic modeling with equations of state: present challenges with established methods 

      Wilhelmsen, Øivind; Aasen, Ailo; Skaugen, Geir; Aursand, Peder; Austegard, Anders; Aursand, Eskil; Gjennestad, Magnus Aashammer; Lund, Halvor; Linga, Gaute; Hammer, Morten (Journal article; Peer reviewed, 2017)
      Equations of state (EoS) are essential in the modeling of a wide range of industrial and natural processes. Desired qualities of EoS are accuracy, consistency, computational speed, robustness and predictive ability outside ...
    • Thermodynamic models to accurately describe the PVTxy-behavior of water / carbon dioxide mixtures 

      Aasen, Ailo; Hammer, Morten; Skaugen, Geir; Jakobsen, Jana Poplsteinova; Wilhelmsen, Øivind (Journal article; Peer reviewed, 2017)
      Carbon dioxide/water (CO2/H2O) mixtures are of much interest in carbon capture and storage, atmospheric science, in the description of human lungs and in the processing of food and beverages. We present a comprehensive ...
    • Understanding the physical phenomena that occur inside heat exchanger for liquefactin of hydrogen 

      Wilhelmsen, Øivind; Skaugen, Geir; Berstad, David Olsson; Aasen, Ailo; Nekså, Petter (Chapter, 2017)
      Liquid hydrogen is an attractive solution for long-range distribution. The largest barriers for implementing large-scale hydrogen liquefaction plants are currently their high energy consumption and cost. The heat exchangers ...
