Arterial Flow and Pulse Wave Propagation in one dimensional Arterial Networks with Statistically Distributed Model Parameters
Eck, Vinzenz Gregor (Master thesis, 2012)Parametric uncertainty in blood flow simulations of cardiovascular systems has received little attention, although methods for blood flow simulation has been subject of many studies. This work presents the implementation ... -
Biomechanical modeling of fetal veins: The umbilical vein and ductus venosus bifurcation
Leinan, Paul Roger (Doktoravhandlinger ved NTNU, 1503-8181; 2012:299, Doctoral thesis, 2012) -
Boundary Conditions for 3D Fluid-Structure Interaction Simulations of Compliant Vessels
Hansen, Merethe Sirevåg (Master thesis, 2013)The goal of this study was to investigate different outlet boundary conditions for a straight compliant tube, by the means of fluid-structure interaction simulations. In addition to investigating boundary conditions it was ... -
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). ... -
Experimental Investigation of Rhinomanometry
Aanderaa, Lea Øvensen (Master thesis, 2021) -
Mathematical Modelling and Simulation of Flow in Collapsible Tubes
Akbar, Batool (Master thesis, 2022)Obstruktiv søvnapné (OSA) er en tilstand som midlertidig blokkerer luftstrømmen gjennom de øvre luftveiene under søvn for de som er rammet. Denne vanlige tilstanden kan redusere søvn og livskvalitet, og til og med føre til ... -
Repeatability in a multiphase pipe flow case study
Strand, Andreas; Brekken, Christian; Leinan, Paul Roger; Steinsland, Ingelin; Hellevik, Leif Rune (Peer reviewed; Journal article, 2021)A high degree of repeatability is most often an underlying assumption for research and development based on multiphase flow experiments. In this paper repeatability in multiphase flow experiments are studied through an ... -
The Time Varying Elastance Model used as a Boundary Condition in Arterial Network Simulations
Maråk, Knut Petter (Master thesis, 2013)Vascular1Dflow is a program for simulating blood flow in vascular networks. It uses hyperbolic one-dimensional partial differential equations with ordinary differential equations as boundary conditions. The focus of 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 (Chapter, 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) ...
