CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2
Aursand, Eskil; Aursand, Peder; Berstad, Torodd; Dørum, Cato; Hammer, Morten; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2013)We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ... -
CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods
Aursand, Eskil; Dørum, Cato; Hammer, Morten; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2014)One challenge in CCS is related to the prevention of running-ductile fracture in CO2-carrying pipelines. Commonly used tools for ensuring crack arrest in pipelines hinge mainly on semi-empirical models, which may not be ... -
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 ... -
Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model
Aursand, Eskil; Dumoulin, Stephane; Hammer, Morten; Lange, Hans Iver; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Journal article; Peer reviewed, 2016)Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO2 is transported. To overcome this, a coupled fluid-structure ... -
Liquid Hydrogen Spills on Water—Risk and Consequences of Rapid Phase Transition
Odsæter, Lars Hov; Skarsvåg, Hans Langva; Aursand, Eskil; Ustolin, Federico; Reigstad, Gunhild Allard; Paltrinieri, Nicola (Peer reviewed; Journal article, 2021)Liquid hydrogen (LH2 ) spills share many of the characteristics of liquefied natural gas (LNG) spills. LNG spills on water sometimes result in localized vapor explosions known as rapid phase transitions (RPTs), and are a ... -
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) -
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 risk for rapid phase transition in LNG spilled on water : an overview of the Predict-RPT project
Reigstad, Gunhild Allard; Lervåg, Karl Yngve; Aursand, Eskil (SINTEF Rapport;, Research report, 2020) -
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 ...
