Experimental and numerical analysis of carotid artery blood flow

To obtain more insight into the complex blood flow patterns in the carotid artery bifurcation numerical analyses, limited to Newtonian incompressible flows in rigid-wall geometries, have been carried out combined with laser-Doppler velocity measurements. The steady and unsteady flow in two-dimensional models of a stenosis and of the carotid artery bifurcation were analysed. As a first step to a three-dimensional analysis, the steady flow development in a curved tube was investigated
