Variational Data Assimilation - Towards Robust Vector Flow Estimation with Ultrasound
In vitro validation of ultrasound VFI regularization through rapid data assimilation
The effect of chordae tendineae on systolic flow
When using Computational Fluid Dynamics to simulate ventricular blood flow in the heart, it has been common practice to neglect the effect of the sub-valvular apparatus and the trabeculae on the flow conditions. In this study, we analyze the effect of neglecting the chordae tendineae on the fluid fl...
Observations of Rising Methane Bubbles in Trondheimsfjord and Its Implications to Gas Dissolution
Gas dissolution reduces the release of methane to the atmosphere from subsea sources. Being able to predict and assess the methane flux to the atmosphere requires knowledge on gas dissolution and mass transfer. This can be obtained by studying the size evolution of bubbles rising in water. New data ...
Large Scale PEM Electrolysis Stack Development - the Megastack Project
Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling
In petroleum drilling, aqueous Polyanionic Cellulose solutions (PAC) are often used as a drilling fluid model system in experimental laboratory studies to investigate cuttings transport. Cuttings transport refers to the transportation of drilled-off solids out of the wellbore. In these studies, PAC ...
Comparison of Meso Scale Subsea gas Release With Multiphase Eulerian-Lagrangian CFD Model
We compare the observed dynamics of subsea starting plumes with multiphase computational fluid dynamics (CFD) simulations. In the event of subsea loss of containment of either natural gas or carbon dioxide it is important to understand how the gas disperses in the ocean column and acends to the surf...
