Theory and simulation of shock waves: Entropyproduction and energy conversion
Bjørn Hafskjold, Dick Bedeaux, Øivind Wilhelmsen +1
We have considered a shock wave as a surface of discontinuity and computed the entropy production using non-equilibrium thermodynamics for surfaces. The results from this method, w…
Thermodynamic properties of the 3D Lennard-Jones/spline model
Bjørn Hafskjold, Karl Patrick Travis, Amanda Bailey Hass +3
The Lennard-Jones (LJ) spline potential is a truncated LJ potential such that both the pair potential and the force continuously approach zero at . We present a…
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…
