Original abstract

Computational simulations can be used to better predict the risk of atherosclerotic plaques (atheromas) formation. The study presents three-dimensional patient specific computational models of blood hemodynamic in the human carotid arteries based on finite volume method. The geometry of the arteries was created from computer tomography (CT) images. Measured mass flow rate waveform at the inlet and two-element Winkessel model at the outlets are used as boundary conditions. Blood is considered as a non-Newtonian fluid described by Carreau model and pulsating blood flow is solved by transient analysis. Time history of wall shear stress magnitude, velocity profiles in individual cross-sections and flow pattern are evaluated and discussed as they may be helpful in assessing the risk of potential development of atheroma.
