Abstract

In order to properly account for the unsteady nature of the flow field generated by the cardiac ejection in an Aortic Arch with an implanted Left Ventricular Assist Device (LVAD) Computational Fluid Dynamics (CFD) model, a closed-loop external vascular model is necessary. Such external model is coupled to the CFD model to dictate the flow field boundary conditions at the outlets of the CFD model and thus, control the flow splits through the different branches that stem out of the aortic arch throughout the cardiac cycle.
