Blood Flows in Vascular Networks: Numerical Results vs Experimental Data

The goal of this work is to compare the numerical results calculated by the 1D blood flow model with experimental data. In the first case the fluid flow in the network of silicone tubes is simulated. Numerical results are in good agreement with measured experimental data. We showed that neglecting tapered vessel form helps to save computational time without significant loss of results quality. In the second case the fluid flow in the bifurcation of carotid arteries is simulated. The model was not able to reproduce the experimental data because of fluid flow complexity. Boundary conditions at bifurcation node should be refined for this case.
