HLLC-type methods for compressible two-phase flow in ducts with discontinuous area changes
Log, Alexandra Metallinou; Munkejord, Svend Tollak; Hammer, Morten (Peer reviewed; Journal article, 2021)In this work, the Harten-Lax-van Leer Contact (HLLC) approximate Riemann solver is extended to two-phase flow through ducts with discontinuous cross-sections. Two main strategies are explored regarding the treatment of the ... -
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 ... -
Method using a density-energy state function with a reference equation of state for fluid-dynamics simulation of vapor-liquid-solid carbon dioxide
Hammer, Morten; Ervik, Åsmund; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2013)With the advent of CO2 capture and storage (CCS) as an important remedy for reducing atmospheric CO2 emissions, it has become necessary to develop accurate and efficient simulation tools. Among other things, such tools ... -
Predicting triggering and consequence of delayed LNG RPT
Aursand, Eskil; Hammer, Morten (Journal article; Peer reviewed, 2018)Predicting triggering and consequence of delayed LNG RPT -
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 ... -
Thermo-Fluid-Dynamical Modelling of Salt Precipitation During Co2 Injection in Saline Aquifers, and the Effect on Injectivity
Ervik, Åsmund; Lund, Halvor; Hammer, Morten; Aasen, Ailo; Matas, Berta Güell (Journal article, 2019) -
Thermodynamic properties of the 3D Lennard-Jones/spline model
Hafskjold, Bjørn; Travis, Karl; Bailey, Amanda H.; Hammer, Morten; Aasen, Ailo; Wilhelmsen, Øivind (Journal article; Peer reviewed, 2019)In the Lennard-Jones spline (LJ/s) model, the Lennard-Jones (LJ) potential is truncated and splined so that both the pair potential and the force continuously approach zero at rc 1:74 . It exhibits the same structural ... -
Towards a thorough Validation of Simulation Tools for CO2 Pipeline Transport
Drescher, Michael; Fahmi, Adil; Aursand, Peder; Hammer, Morten; Lund, Halvor; Stang, Hans Georg Jacob; Austegard, Anders (Journal article; Peer reviewed, 2017)In this work the Schlumberger flow assurance tool OLGA and SINTEF Energy Research in-house CFD tool are assessed for their ability to describe depressurization behaviour of CO2 pipelines. For this purpose, three full-bore ... -
Upward and downward two-phase flow of in a pipe: Comparison between experimental data and model predictions
Hammer, Morten; Deng, Han; Liu, Lan; Langsholt, Morten Chr.; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2021)In order to deploy capture and storage (CCS) systems to mitigate climate change, it is crucial to develop reliable models for design and operational considerations. A key element of the system is the interface between ... -
Well integrity for CO2 injection from ships: Simulation of the effect of flow and material parameters on thermal stresses
Aursand, Peder; Hammer, Morten; Lavrov, Alexandre; Lund, Halvor; Munkejord, Svend Tollak; Torsæter, Malin (Journal article; Peer reviewed, 2017)Ships have been shown to be the most cost-effective way to transport CO2 from many sources in the Nordic region to offshore storage sites. Injection from ships introduces new challenges for the integrity of CO2 injection ...
