CFD Challenge: Computational Hemodynamics Analysis of Patient-Specific Internal Carotid Artery Aneursym Using an In-House Finite Difference Cardiovascular Flow Solver

An important focus of our cardiovascular fluid mechanics studies is the development and application of computational fluid dynamics (CFD) tools for patient-specific evaluation of internal hemodynamics in vascular anatomies. The validated unsteady internal flow solver utilized in this study has been applied to a multitude of cardiovascular geometries, particularly Fontan surgical anastomoses, pediatric venous flow confluences ¹, idealized developing embryonic chick-heart models ², neonatal aortic arch models and several complex geometries involving jet flow behavior ³. We have also recently started to explore the capability of this solver for evaluating internal flows and wall shear stresses in abdominal aortic aneursyms. For the 2012 SBC Challenge, 3D transient CFD simulations have been performed for a patient-specific internal carotid artery aneurysm case.
