Numerical investigation on the effect of different strut angle to the cerebral aneurysm

The objective of this study was to determine the correlation of stent strut angle to blood flow and also to determine the flow behavior in stented aneurysm. The computational fluid dynamics was applied to access the changes of velocity and pressure in aneurysms. For this study, there are five stent...
