Key result
Varying the Reynolds number (410 < Re < 2650) in an in vitro abdominal aortic aneurysm model showed that the recirculation zone moves downstream and peak wall shear stress decreases with increasing Re.
This in vitro study provides high-resolution data on hemodynamics in abdominal aortic aneurysms, demonstrating that wall shear stress peaks at the reattachment point and varies inversely with Reynolds number.

In vitro AAA flow data warrant no clinical change; leaves open translation to patient-specific hemodynamics.
Espa et al. (2019) studied Abdominal aortic aneurysm. Varying Reynolds number (410 < Re < 2650) was evaluated on Wall shear stress distribution and blood flow patterns. Varying the Reynolds number (410 < Re < 2650) in an in vitro abdominal aortic aneurysm model showed that the recirculation zone moves downstream and peak wall shear stress decreases with increasing Re.
