• Short-Range Structure of Ti0.63V0.27Fe0.10D1.73 from Neutron Total Scattering and Reverse Monte Carlo Modelling 

      Mauroy, Henrik; Klyukin, Konstantin; Shelyapina, Marina G.; Keen, David A.; Thøgersen, Annett; Hauback, Bjørn; Sørby, Magnus Helgerud (Peer reviewed; Journal article, 2020)
      Ti-V-based body-centered cubic (BCC) alloys have potential for large-scale hydrogen storage if expensive vanadium is substituted with much cheaper Fe-containing ferrovanadium. Use of ferrovanadium reduces the alloys’ ...
    • Simulation of stress hysteresis effect on permeability increase risk along a fault 

      Rongved, Mats; Cerasi, Pierre (Journal article; Peer reviewed, 2019)
      CO2 sequestration projects will in the coming years include both aquifer and depleted oil and gas field sites, with different stress paths and history. Stress changes and stress concentration effects on faults will have ...
    • A Study on Bio-Coke Production—The Influence of Bio-Components Addition on Coke-Making Blend Properties 

      Rejdak, Michał; Wojtaszek-Kalaitzidi, Małgorzata; Gałko, Grzegorz; Mertas, Bartosz; Radko, Tomasz; Baron, Robert; Ksiazek, Michal Tomasz; Larsen, Sten Yngve; Sajdak, Marcin; Kalaitzidis, Stavros (Peer reviewed; Journal article, 2022)
      Due to global warming, technologies reducing CO2 emissions in the metallurgical industry are being sought. One possibility is to use bio-coke as a substitute for classic coke made of 100% fossil coal. Bio-coke can be ...
    • Use of concentric hele-shaw cell for the study of displacement flow and interface tracking in primary cementing 

      Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)
      We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress ...
    • Verification of heat and mass transfer closures in industrial scale packed bed reactor simulations 

      Singhal, Arpit; Cloete, Schalk Willem Petrus; Quinta-Ferreira, Rosa; Amini, Shahriar (Journal article; Peer reviewed, 2018)
      Particle-resolved direct numerical simulation (PR-DNS) is known to provide an accurate detailed insight into the local flow phenomena in static particle arrays. Most PR-DNS studies in literature do not account for reactions ...
    • Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use 

      Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2020)
      An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ...
    • Wet Drilled Cuttings Bed Rheology 

      Pedrosa, Camilo; Saasen, Arild; Lund, Bjørnar; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)
      The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ...
