A fracture-propagation-control model for pipelines transporting CO2-rich mixtures including a new method for material-model calibration
(Journal article; Peer reviewed, 2017)This work considers a predictive numerical modelling approach for fracture-propagation control in CO2-transport pipelines, an area where current engineering tools do not work. Fluid-structure interaction model simulations ... -
CO2 Pipeline Integrity: Comparison of a Coupled Fluid-structure Model and Uncoupled Two-curve Methods
(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 ... -
Combining thermodynamic and fluid flow modelling for CO2 flow assurance
(Journal article; Peer reviewed, 2013)The present paper concerns the importance of a combined modelling and experimental effort to develop physicsbased combined thermodynamic and transient flow models for CO2-transport pipelines. Such models need to handle ... -
Depressurization of CO2 in a pipe: Effect of initial state on non-equilibrium two-phase flow
(Peer reviewed; Journal article, 2023)It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ... -
Depressurization of CO2-rich mixtures in pipes: Two-phase flow modelling and comparison with experiments
(Journal article; Peer reviewed, 2015)We present and discuss two-phase flow models to simulate transient flow of CO2-rich mixtures in pipes, which is of relevance for design, operation and safety. The model predictions are compared to data from five depressurization ... -
HLLC-type methods for compressible two-phase flow in ducts with discontinuous area changes
(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 ... -
