Mathematical modelling of blood flow in arterial bifurcations

Pulsatile blood flow in anatomically correct models of arterial bifurcations is simulated numerically. The computational geometric models are developed on the basis of optically digitized casts. A finite element grid generation procedure based on optimization of local grid properties has been developed. The flow dynamics is described applying the incompressible Navier-Stokes equations for non-Newtonian inelastic fluids. The description of the vessel wall mechanics uses geometrically non-linear shell theory. The study demonstrates the importance of anatomically correct models in detailed arterial flow analysis
