Wall Shear Stress-Based Hemodynamic Descriptors in the ‎Abdominal Aorta Bifurcation: Analysis of a Case Study

The knowledge of hemodynamic behaviour in the abdominal aorta artery bifurcation is of great ‎importance for the early diagnosis of several cardiovascular diseases common in this bifurcation. The ‎work developed focuses on a case study of hemodynamic in the abdominal aorta artery bifurcation, ‎based...
