International Workshop on Non-Equilibrium Thermodynamics in Porous Media

Welcome to the international worshop on non-equilibrium thermodynamics in porous media!

On the occasion of:

Professor Signe Kjelstrup’s 70th Birthday

August 29-30, 2019

PoreLab, NTNU, Trondheim, Norway

Focus and Scope

Over many years Signe Kjelstrup has been pioneering the foundation and the application of non-equilibrium thermodynamics. Regarding the fundamentals she contributed to the verification of local equilibrium, the development of mesoscopic thermodynamics to describe active transport and the extension of non-equilibrium thermodynamics to transport into and through surfaces. The theory has over the years actively been verified by applying it to electrochemical cells, membrane systems as well as for distillation columns by entropy production minimization. Effort has also been made to the use of non-equilibrium molecular dynamics to study these systems on a molecular level. The validity of the Onsager relations in homogeneous phases as well as for surfaces was verified in this manner.

In recent years the application of the methods of non-equilibrium thermodynamics to porous media has been the focus of Signe Kjelstrup’s work. Using that multi-phase flow through porous media is Euler homogeneous, it has been possible to obtain expressions for the entropy production on the macro level. The resulting dynamic description has been studied. An important recent achievement is the definition of two pressures in a nanoporous medium. Much important work is still to be done.

The workshop will review the highlights of the work done in the PoreLab Center of Excellence.
