Abstract

Numerical simulations investigating the mechanics of blood flow through elastic arteries have demonstrated the significance of haemodynamics study in the cardiovascular flows. The present study investigates the flow behavior in an idealistic abdominal aorta with renal bifurcation obtained from the computed tomography (CT) image data. Geometric model is generated using ANSYS design modeler and numerical analysis is investigated using FSI technique in ANSYS-17. The fluid domain representing the blood flow is Newtonian, incompressible, and homogenous, while the solid domain representing the arterial wall is linearly elastic. The time varying two-way interacting sequentially coupled field simulation is carried out using FSI solver. The present study investigates the haemodynamic parameters to understand the influence of flow changes at the renal bifurcation region. The flow behavior is compared at rest and exercise conditions throughout pulsatile flow and the considerable changes are observed through the results obtained. This fundamental study shall be useful to understand the flow behavior in patient-specific cases.
