Název v původním jazyce

Pulsatile non-Newtonian blood flow in image-based models of carotid bifurcation

Popis výsledku v původním jazyce

Present hemodynamical study is motivated by the ongoing clinical research at the University Hospital in Pilsen, Czech Republic. On the basis of provided CT scans, several carotid artery models were reconstructed and used for this numerical study of pulsatile blood flow. The blood is modelled as a shear-dependent incompressible fluid, motion of which is described by the non-linear system of Navier-Stokes equations coupled with the Carreau-Yasuda model. The mathematical model is solved using in-house software based on the principle of the SIMPLE algorithm and cell-centred finite volume method (FVM) formulated for hybrid unstructured tetrahedral grids. The discussion of obtained numerical results is performed with special emphasis placed on the analysis of velocity field and distribution of main hemodynamic factors such as cycle-averaged WSS and oscillatory shear index (OSI) in areas prone to atherosclerosis.
