The effect of stent void area on hemodynamics in cerebral aneurysm

The purpose of this study is to develop modeling methodologies to understand how different stent void area alter the aneurysmal flow. Four difference stents design with difference void area were created with suitable geometry for Computational Fluid Dynamics (CFD) analysis. The velocity profile and...
