Sažetak

The cardiovascular disease is one of most frequent cause deaths in modern society. The objective of this work is analyse
the effect of dynamic vascular geometry (curvature, torsion,bifurcation) and pulsatile blood nature on secondary
flow, wall shear stress and platelet deposition. The problem was examined as multi-scale physical phenomena using perturbation
analysis and numerical modelling. The secondary flow determined as influence pulsatile pressure, vascular
tube time-dependent bending and torsion on the main axial flow. Bifurcation and branching phenomena are analysed
experimentally through, blood-like fluid pulsatile flow across elastic rubber-like Y-model model. The problem complex
geometry near branching in platelet deposit modelling is resolved numerically as Falker-Skan flow.
