Comparison of ultrasound vector flow imaging and CFD simulations with PIV measurements of flow in a left ventricular outflow trackt phantom - Implications for clinical use and in silico studies
Leinan, Paul Roger; Grønli, Thomas; Skjetne, Paal; Wigen, Morten Smedsrud; Urheim, Stig; Løvstakken, Lasse; Dahl, Sigrid Kaarstad (Peer reviewed; Journal article, 2022)In this study we have compared two modalities for flow quantification from measurement data; ultrasound (US) and shadow particle image velocimetry (PIV), and a flow simulation model using computational fluid dynamics (CFD). ... -
The effect of chordae tendineae on systolic flow
Morud, John; Skjetne, Paal; Urheim, Stig; Dahl, Sigrid Kaarstad (Journal article; Peer reviewed, 2019)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 ... -
Velocity profiles in a 2D model of the left ventricular outflow tract, pathological case study using PIV and CFD modeling
Leinan, Paul Roger; Skjetne, Paal; Morud, John; Urheim, Stig; Dahl, Sigrid Kaarstad (SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)In the current study, we present an experimental (in vitro) 2D flow model for studying blood flow in the human left ventricular outflow tract (LVOT) and the first part of the aorta using particle image velocimetry (PIV) ...
