Comparisons of hemodynamic characteristics in the extracted aneurysmal sac between simplified Newtonian and realistic non-Newtonian blood viscosity models at representative time instants (i.e., t1 = 0.072 s, t2 = 0.162 s, t3 = 0.312 s, t4 = 0.662 s, and t5 = 0.952 s): (a) realistic non-Newtonian blood. (b) Simplified Newtonian blood.
