Thermal performance estimation for cryogenic storage tanks: Application to liquid hydrogen
Ailo Aasen, Sindre Stenen Blakseth, André Massing +2
The design of cryogenic liquid storage solutions requires accurate methods for estimating heat ingress, from the material level to the tank level. For insulation materials, thermal…
A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transitions in LNG spills
Karl Yngve Lervåg, Hans L. Skarsvåg, Eskil Aursand +8
Transport of liquefied natural gas (LNG) by ship occurs globally on a massive scale. The large temperature difference between LNG and water means LNG will boil violently if spilled…
Onsager-Symmetry Obeyed in Athermal Mesoscopic Systems: Two-Phase Flow in Porous Media
Mathias Winkler, Magnus Aa. Gjennestad, Dick Bedeaux +3
We compute the fluid flow time-correlation functions of incompressible, immiscible two-phase flow in porous media using a 2D network model. Given a properly chosen representative e…
Pore network modeling of the effects of viscosity ratio and pressure gradient on steady-state incompressible two-phase flow in porous media
Magnus Aa. Gjennestad, Mathias Winkler, Alex Hansen
We perform more than 6000 steady-state simulations with a dynamic pore network model, corresponding to a large span in viscosity ratios and capillary numbers. From these simulation…
Thermodynamic stability of droplets, bubbles and thick films in open and closed pores
Magnus Aa. Gjennestad, Øivind Wilhelmsen
A fluid in a pore can form diverse heterogeneous structures. We combine a capillary description with the cubic-plus-association equation of state to study the thermodynamic stabili…
A Dynamic Network Simulator for Immiscible Two-Phase Flow in Porous Media
Santanu Sinha, Magnus Aa. Gjennestad, Morten Vassvik +1
We present in detail a set of algorithms to carry out fluid displacements in a dynamic pore-network model of immiscible two-phase flow in porous media. The algorithms are general a…
Performance analysis of heat and energy recovery ventilators using exergy analysis and nonequilibrium thermodynamics
Magnus Aa. Gjennestad, Eskil Aursand, Elisa Magnanelli +1
The increased attention to energy savings has contributed to more widespread use of energy recovery systems for building ventilation. We investigate the efficiency of such systems…
Stable and efficient time integration of a dynamic pore network model for two-phase flow in porous media
Magnus Aa. Gjennestad, Morten Vassvik, Signe Kjelstrup +1
We study three different time integration methods for a dynamic pore network model for immiscible two-phase flow in porous media. Considered are two explicit methods, the forward E…
Rheology of High-Capillary Number Flow in Porous Media
Santanu Sinha, Magnus Aa. Gjennestad, Morten Vassvik +3
Immiscible fluids flowing at high capillary numbers in porous media may be characterized by an effective viscosity. We demonstrate that the effective viscosity is well described by…
Relations between Seepage Velocities in Immiscible, Incompressible Two-Phase Flow in Porous Media
Alex Hansen, Santanu Sinha, Dick Bedeaux +3
Based on thermodynamic considerations we derive a set of equations relating the seepage velocities of the fluid components in immiscible and incompressible two-phase flow in porous…
Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme
Magnus Aa. Gjennestad, Andrea Gruber, Karl Yngve Lervåg +4
We have developed a high-order numerical method for the 3D simulation of viscous and inviscid multiphase flow described by a homogeneous equilibrium model and a general equation of…
A multi-phase ferrofluid flow model with equation of state for thermomagnetic pumping and heat transfer
Eskil Aursand, Magnus Aa. Gjennestad, Karl Yngve Lervåg +1
A one-dimensional multi-phase flow model for thermomagnetically pumped ferrofluid with heat transfer is proposed. The thermodynamic model is a combination of a simplified particle…

Eskil Aursand, Magnus Aa. Gjennestad, Karl Yngve Lervåg +1
The feasibility of using a thermomagnetically pumped ferrofluid to enhance the performance of a natural convection cooling loop is investigated. First, a simplified analytical esti…
