Techno-economic optimization of hybrid steam-electric energy systems with excess heat utilization and reserve market participation

Olav Galteland, Jacob Hadler-Jacobsen, Hanne Kauko

This study investigates the economic viability and optimal configuration of a hybrid industrial energy system combining an electrode boiler, steam accumulator, and battery energy s…

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…

Legendre-Fenchel transforms capture layering transitions in porous media

Olav Galteland, Eivind Bering, Kim Kristiansen +2

We have investigated the state of a nanoconfined fluid in a slit pore in the canonical and isobaric ensembles. The systems were simulated with molecular dynamics simulations. The f…

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…
