Grahic Jump Location
Schematic illustration of the Carotid bifurcation model showing the branch configuration and the coordinate system. The physical dimensions of the branches are Rcom=0.4 [cm],Rint=0.6942Rcom and Rext=0.5778Rcom.
Grahic Jump Location
Comparison of velocity profiles on the vessel symmetry plane for several positions between the bifurcation and the ICA and ECA outlets. The Full Model refers to that with outlet branches of length 24Rcom(12Dcom) while the Shortened Model refers to that with outlet branches of length 12Rcom(6Dcom).
Grahic Jump Location
Comparison of wall shear stress contours in the vicinity of the bifurcation for the Full Model and the Shortened Model. The label values have units of [dynes/cm2].
Grahic Jump Location
Evolution of the average pressure on the ECA face for steady computations. Results are shown for the Shortened Model.
