Description
Summary:This work compares the coronary artery hemodynamics, considering rigid and deformable arterial wall throughout a cardiac cycle. A patient-specific study was performed using computational fluid dynamics (CFD) and fluid-structure interaction (FSI) method. The simulations were run through an In-House OpenFOAM software and the commercial ANSYS (R) software for validation. The velocity magnitude, at systolic peak, was achieved in several locations, considering CFD and FSI. The major difference was verified in the bifurcation. The dynamic behavior results in a global reduction of 3.5% due to the increase of the fluid domain.
