Numerical and Experimental Investigation of Novel Blended Bifurcated Stent Grafts with Taper to Improve Hemodynamic Performance

Figure 2

(a) Helicity isosurfaces of −0.5/0.5 ms⁻² under steady-state simulation. (b) Surface contours of helicity at the left iliac graft outlet steady-state simulation. The right-handed helical structure with positive value was colored red, while the left-handed helical structure with negative value was colored blue.
