• A molecular dynamics study of prolate ellipsoidal nanoparticles adsorbed at liquid-vapour interfaces 

      Galteland, Olav (Master thesis, 2017)
      Nanoparticles may adsorb strongly at liquid-vapour interfaces and form layers, which may be a source for new and interesting materials. It is not fully understood how the nanoparticles adsorbed at the interface interact, ...
    • Gibbs ensemble Monte Carlo simulation of fluids in confinement: Relation between the differential and integral pressures 

      Erdős, Máté; Galteland, Olav; Bedeaux, Dick; Kjelstrup, Signe; Moultos, Othonas A.; Vlugt, Thijs J.H. (Peer reviewed; Journal article, 2020)
      The accurate description of the behavior of fluids in nanoporous materials is of great importance for numerous industrial applications. Recently, a new approach was reported to calculate the pressure of nanoconfined fluids. ...
    • Nanothermodynamic Description and Molecular Simulation of a Single-Phase Fluid in a Slit Pore 

      Galteland, Olav; Bedeaux, Dick; Kjelstrup, Signe (Peer reviewed; Journal article, 2021)
      We have described for the first time the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill’s thermodynamics of small systems. Hill’s theory has been named ...

      Galteland, Olav (Doctoral theses at NTNU;2022:144, Doctoral thesis, 2022)
      The thermodynamic and transport properties of fluids confined to porous media are in this thesis investigated with nanothermodynamics, non-equilibrium thermodynamics, and molecular simulations. Non-equilibrium thermodynamics ...
    • Nanothermodynamics of a Single-Phase Fluid Confined in a Complex Porous Medium 

      Varughese, Kevin Kottakkakathu (Master thesis, 2021)
      Nanotermodynamiske teorier og ideer blir her brukt på små systemer, spesifikt et porøsmedium, ved hjelp av Monte Carlo simulasjoner med Molekylær Dynamikk basert på "Grand Canonical Ensemble". Til å begynne med tester vi ...
    • Non-isothermal transport of multi-phase fluids in porous media. Constitutive equations 

      Kjelstrup, Signe; Bedeaux, Dick; Hansen, Alex; Hafskjold, Bjørn; Galteland, Olav (Peer reviewed, Journal article, 2019)
      We define a representative elementary volume of a porous medium in terms of lumped extensive variables, including properties of homogeneous phases, interfaces, and contact lines. Using the grand potential, we define the ...
    • Non-isothermal transport of multi-phase fluids in porous media; The entropy production 

      Kjelstrup, Signe; Bedeaux, Dick; Hansen, Alex; Hafskjold, Bjørn; Galteland, Olav (Journal article; Peer reviewed, 2018)
      We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Thermodynamic extensive variables on the ...
    • Pressures Inside a Nano-Porous Medium. The Case of a Single Phase Fluid 

      Galteland, Olav; Bedeaux, Dick; Hafskjold, Bjørn; Kjelstrup, Signe (Journal article; Peer reviewed, 2019)
      We define the pressure of a porous medium in terms of the grand potential and compute its value in a nano-confined or nano-porous medium, meaning a medium where thermodynamic equations need be adjusted for smallness. On ...
    • Pressures inside a nano-porous medium. The case of a single phase fluid 

      Galteland, Olav; Kjelstrup, Signe; Bedeaux, Dick (Research report, 2018)
      We define the pressure of a porous medium in terms of the grand potential, and compute its value in a nano-confined or nano-porous medium, meaning a medium where thermodynamic equations need be adjusted for smallness. On ...
    • The permeability of porous media as studied by NEMD 

      Bratvold, Mina Sørensen (Master thesis, 2021)
      Det overordnede målet med prosjektet er å bidra til å etablere en beskrivelse av irreversibel termodynamikk for nano-skalaen. Mer spesifikt defineres tilstandsvariabler for fluid som er innesluttet i porøse medier, kunnskapen ...
    • Two-Phase Equilibrium Conditions in Nanopores 

      Rauter, Michael Tobias; Galteland, Olav; Erdos, Mate; Moultos, Othonas A.; Vlugt, Thijs J.H.; Schnell, Sondre Kvalvåg; Bedeaux, Dick; Kjelstrup, Signe (Peer reviewed; Journal article, 2020)
      It is known that thermodynamic properties of a system change upon confinement. To know how, is important for modelling of porous media. We propose to use Hill’s systematic thermodynamic analysis of confined systems to ...
