Mathematical Models and Numerical Simulations for the Blood Flow in Large Vessels

Two and Three Dimensional Blood Flow Simulations in Different Types of Blood Vessels

“…The analyzed rupture takes place when this internal stress of the boundary (in our case given by the general Maxwell model for viscoelasticity) is overpassed by the so-called "wall shear stress" (WSS) evaluated on the considered boundary. Let us now accept again as we did in our previous researches (Albert et al 2013 [1], Petrila et al 2014 [13]), that the blood flow in the considered vessel (under a pulsatile regime connected with the rhythmic pumping of the blood by the heart) has a nonNewtonian behavior with variable viscosity. More precisely the plasma viscosity is given by the Cross model, i.e.…”
