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…
A consistent reduction of the two-layer shallow-water equations to an accurate one-layer spreading model
Eirik Holm Fyhn, Karl Yngve Lervåg, Åsmund Ervik +1
The gravity-driven spreading of one fluid in contact with another fluid is of key importance to a range of topics. To describe these phenomena, the two-layer shallow-water equation…
A multiscale method for simulating fluid interfaces covered with large molecules such as asphaltenes
Åsmund Ervik, Morten Olsen Lysgaard, Carmelo Herdes +4
(Abbreviated) In this paper we report on the development of a multiscale method for simulating complex liquid-liquid systems such as water in contact with oil containing asphaltene…
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…
Curvature calculations for the level-set method
Karl Yngve Lervåg, Åsmund Ervik
The present work illustrates a difficulty with the level-set method to accurately capture the curvature of interfaces in regions that are of equal distance to two or more interface…
Extending a serial 3D two-phase CFD code to parallel execution over MPI by using the PETSc library for domain decomposition
Åsmund Ervik, Svend Tollak Munkejord, Bernhard Müller
To leverage the last two decades' transition in High-Performance Computing (HPC) towards clusters of compute nodes bound together with fast interconnects, a modern scalable CFD cod…
