Local thermodynamic description of isothermal single-phase flow in porous media
Olav Galteland, Michael T. Rauter, Mina S. Bratvold +3
Darcy's law for porous media transport is given a new local thermodynamic basis in terms of the grand potential of confined fluids. The local effective pressure gradient is determi…
Defining the pressures of a fluid in a nanoporous, heterogeneous medium
Olav Galteland, Michael T. Rauter, Kevin K. Varughese +2
We describe the thermodynamic state of a single-phase fluid confined to a porous medium with Hill's thermodynamics of small systems, also known as nanothermodynamics. This way of d…
Nanothermodynamic description and molecular simulation of a single-phase fluid in a slit pore
Olav Galteland, Dick Bedeaux, Signe Kjelstrup
We describe the thermodynamic state of a highly confined single-phase and single-component fluid in a slit pore using Hill's thermodynamics of small systems. This theory was more r…
Pressures inside a nano-porous medium. The case of a single phase fluid
Olav Galteland, Dick Bedeaux, Signe Kjelstrup
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 equa…
Non-isothermal transport of multi-phase fluids in porous media. Constitutive equations
Signe Kjelstrup, Dick Bedeaux, Alex Hansen +2
We develop constitutive equations for multi-component, multi-phase, macro-scale flow in a porous medium exposed to temperature-, composition-, and pressure -gradients. The porous m…
Non-isothermal transport of multi-phase fluids in porous media. The entropy production
Signe Kjelstrup, Dick Bedeaux, Alex Hansen +2
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. Th…
