A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transitions in LNG spills
Lervåg, Karl Yngve; Skarsvåg, Hans Langva; Aursand, Eskil; Ouassou, Jabir Ali; Hammer, Morten; Reigstad, Gunhild Allard; Ervik, Åsmund; Fyhn, Eirik Holm; Gjennestad, Magnus Aashammer; Aursand, Peder; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2020)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 onto water. This may cause a physical ... -
Computation of three-dimensional three-phase flow of carbon dioxide using a high-order WENO scheme
Gjennestad, Magnus Aashammer; Gruber, Andrea; Lervåg, Karl Yngve; Johansen, Øyvind; Ervik, Åsmund; Hammer, Morten; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2017)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 state. Here we focus on single-phase, ... -
Investigation of non-ideal behavior of plate-fin heat exchangers in LNG services
Skaugen, Geir; Hammer, Morten; Gjennestad, Magnus Aashammer (Peer reviewed; Journal article, 2015)Using a heat exchanger with several parallel channels in boiling services, static instabilities like the Ledinegg instabilities can occur, resulting from a combination of unfortunate operating conditions and the heat ... -
Potential of enhancing a natural convection loop with a thermomagnetically pumped ferrofluid
Aursand, Eskil; Gjennestad, Magnus Aashammer; Lervåg, Karl Yngve; Lund, Halvor (Journal article; Peer reviewed, 2016) -
The spinodal of single- and multi-component fluids and its role in the development of modern equations of state
Aursand, Peder; Gjennestad, Magnus Aashammer; Aursand, Eskil; Hammer, Morten; Wilhelmsen, Øivind (Journal article; Peer reviewed, 2016)The spinodal represents the limit of thermodynamic stability of a homogeneous fluid. In this work, we present a robust methodology to obtain the spinodal of multicomponent fluids described even with the most sophisticated ... -
Thermodynamic stability of volatile droplets and thin films governed by the disjoining pressure in open and closed containers
Gjennestad, Magnus Aashammer; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2020)Distributed thin films of water and their coexistence with droplets are investigated using a capillary description based on a thermodynamic fundamental relation for the film Helmholtz energy, derived from disjoining pressure ... -
Thermodynamically consistent modeling of gas flow and adsorption in porous media
Gjennestad, Magnus Aashammer; Wilhelmsen, Øivind (Peer reviewed; Journal article, 2024)In modeling of gas flow through porous media width adsorption, the thermodynamic properties of the adsorbed phase are usually approximated by those of the bulk liquid. Using non-isothermal, gaseous transport of moist air ...
