Our new paper entitled A comparative Study of experiments and theories on Steady-State Evaporation of Water has just been published in Chemical Thermodynamics and Thermal Analysis. A precise description of energy and mass transport across the liquid-vapor interface of water is central in disciplines spanning from climatology to seawater desalination. In the article, we present a critical …
Wednesday, 5th of October, Michael Rauter successfully defended his PhD-thesis entitled: “Fluid Transport through Nanoporous Media in the Presence of Phase Transitions”. The opponents of the thesis were Prof. Rainer Helmig from the University of Stuttgart, and Prof. Amparo Galindo from Imperial College in London. Prof. Ingve Simonsen from NTNU was the thesis administrator. Michael had …
Friday, 30th of September, Vilde successfully defended her PhD-thesis entitled: “Fundamental Aspects of Thermodynamics of Small Systems Investigated Through Molecular Simulations and Theoretical Descriptions”. The opponents of the thesis were Ass. Prof. Christelle Miqueu from the University of Pai & Adour, and Dr. Ivan Latella from Laboratoire Charles Fabry in France. Prof. Astrid de Wijn …
Vegard Jervell has joined the group to pursue a PhD about the driving forces for flow through porous media. Vegard also wrote his Msc. thesis with the group on kinetic gas theory with real interaction potentials and on a critical analysis of the Kempers model for thermal diffusion.
Tage Malby has joined the group to pursue a PhD about the thermo-physical properties of mixtures between hydrogen, neon and helium that can contribute to improve the energy efficiency and reduce the power demand in hydrogen liquefaction processes. Some advantages of using such mixtures as mixed refrigerants at the lowest temperatures in hydrogen liquefaction are: …
Our new paper entitled One-dimensional mathematical modeling of two-phase ejectors: Extension to mixtures and mapping of the local exergy destruction has just been published in Applied Thermal Engineering. The ejector is a process equipment frequently used in refrigeration processes. In the paper, we address the present knowledge gap on the efficiency of ejectors operating with mixtures …

Our new paper entitled Heat to Hydrogen by Reverse Electrodialysis-Using a Non-Equilibrium Thermodynamics Model to Evaluate Hydrogen Production Concepts Utilising Waste Heat has just been published in Energies. In the article, we study reverse electrodialysis heat engines by use of non-equilibrium thermodynamics and modelling. The reverse electrodialysis heat engine (REDHE) is a promising salinity gradient …
From the 16th to the 20th of July, we were in Graz, Austria, to participate at the 32nd European Symposium on Applied Thermodynamics 2022. It was great to meet colleagues and thermodynamic friends from outside of Norway again after the long break due to Covid-19. There were many excellent talks and posters at the conference. …
In our recent paper in the Journal of Chemical Physics entitled “Equation of state for confined fluids“, we present a consistent thermodynamic framework for calculating the thermodynamic properties of confined fluids. Fluids confined in small volumes behave differently than fluids in bulk systems. For bulk systems, a compact summary of the system’s thermodynamic properties is …

Morten and me are so fortunate to be at a research stay at the University of Stuttgart for some months at the moment. Here, we visit the group of Prof. Joachim Gross, head of the Institute of Technical Thermodynamics and Thermal Process Engineering, to learn about density functional theory for fluids, perturbation theory and collaborate …
