Abstract (EN): The present numerical work is about the importance of blood elasticity in the hemodynamics at the macro-scale. The flow in a stenotic bifurcated artery was used as example. The Multimode Phan-Thien-Tanner (PTT) model was implemented in OpenFOAM (R) code to take into account the blood elasticity. In locations where shear rates are higher than 10 s(-1), differences in the velocity field are not observed, considering Multi-mode PTT model (shear-thinning and elastic behaviors of blood) or Carreau model (only shear-thinning behavior). The blood elasticity effect is insignificant. Artery locations where shear rates are lower than 10 s(-1) (near the bifurcation and stenosis) the blood elasticity has an important role on the blood flow pattern.
