• Gas-liquid slug flow in a horizontal concentric annulus, a comparison of numerical simulations and experimental data 

  Friedemann, Christopher; Mortensen, Mikael; Nossen, Jan (Journal article; Peer reviewed, 2019)

  Multiphase flow simulations were run in OpenFOAM utilizing InterFoam, a volume of fluid type solver. A concentric annulus geometry was constructed and periodic boundary conditions were applied to alleviate the requirement ...

• Corrosion, Scaling and Material Selection in Deep Geothermal Wells – Application to IDDP-2 

  Tjelta, Morten; Krogh, Bente Cecilie; Sæther, Sturla; Seiersten, Marion (Journal article; Peer reviewed, 2019)

  In order to make the world’s energy consumption sustainable there is a need for reducing emissions of CO2 and to shift towards renewable energy sources. Geothermal energy has a large potential in certain parts of the world. ...

• Method for detecting aging related failures of process sensors via noise signal measurement 

  Toosi, Topi; Sirola, Miki; Laukkanen, Jarkko; van Heeswijk, Mark; Karhunen, Juha (Journal article; Peer reviewed, 2019)

  In this article we examine the methods for detecting and predicting aging related process sensor failures by analyzing the noise of the sensor output signal. The study uses data from non-differential and differential ...

• In-pile tensile creep of chemical vapor deposited silicon carbide at 300 °C 

  Koyanagi, Takaaki; Terrani, Kurt; Karlsen, Torill Marie; Andersson, Vendi; Sprouster, David; Ecker, Lynne; Katoh, Yutai (Journal article; Peer reviewed, 2019)

• Modelling the Effect of Porous Iron Sulfide Layers on Sour Corrosion Behaviour 

  Amri, Jamel; Kvarekvål, Jon; Tjelta, Morten (Journal article; Peer reviewed, 2019)

  Surface layers and deposits of iron sulfides formed from sour corrosion may exhibit both protective and corrosive properties, depending on the types of iron sulfide formed and the physical structure of the layers. The ...
