Objective: The aim of the study is to perform 3D numerical analysis of blood flow in the carotid artery bifurcation with and without stenoses.

Material and Methods: The analysis is based on the numerical simulation of Navier-Stokes equations. Four cases of carotid bifurcation are considered: common carotid artery (CCA) bifurcation without stenoses, with one, two and three stenoses are presented too. The analysis is performed considering one pulse wave period and it is based on the finite volume discretization of the Navier-Stokes equations.
