Physiological significance of helical flow in the arterial system and its potential clinical applications

X Liu, A Sun, Y Fan, X Deng - Annals of biomedical engineering, 2015 - Springer
Helical flow in the human aorta is possibly a typical example of 'form follows function'in the
vascular system. The helical blood flow may provide guaranties for the inner surface of the …

Lagrangian postprocessing of computational hemodynamics

Helical flow in carotid bifurcation as surrogate marker of exposure to disturbed shear

D Gallo, DA Steinman, PB Bijari, U Morbiducci - Journal of biomechanics, 2012 - Elsevier
The main purpose of the study is to verify if helical flow might be a surrogate marker of the
exposure to disturbed shear in normal carotid bifurcations. Based on hemodynamic …
