Improvement of LedaFlow for churn flow in vertical pipes
An experimental study of vertical two-phase flow was conducted at the SINTEF Multiphase Laboratory using a 51 meter long 4" pipe at system pressures of 45 and 70 bara. This campaign was conducted as part of a project aimed at improving the physical models in LedaFlow for near-vertical pipes, and was...

Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model
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 interaction model has been developed. It consists of a homegeneous...
Liquid loading and multiple solutions in vertical flows, experiments and modelling with LedaFlow
An experimental study of vertical two-phase flow was conducted at the SINTEF Multiphase Laboratory using a 55 meter long 4" pipe at system pressures of 20, 45 and 70 bara. One of the main objectives of the campaign was to identify regions with multiple solutions, where two flow regimes can coexist...
A two-fluid four-equation model with instantaneous thermodynamical equilibrium
We consider an equilibrium version of a common two-fluid model for pipe flow, containing one mixture mass equation and one mixture energy equation. This model can be derived from a five-equation model with instantaneous thermal equilibrium, to which additional phase relaxation terms are added. An...
