This thesis employs Computational Fluid Dynamics (CFD) simulation technology to solve three flow problems: (1) Blood flow in a Bidirectional Glenn Shunt and a combined Bidirectional Glenn Shunt (BGS) and Blalock-Taussing (BT) Shunt. This shunt is used to address the problem of Cyanosis or “Blue Baby Syndrome,” which is an infant disorder that affects the newly born babies whose skins turn blue or purple because of lack of necessary blood flow between heart and lung due to pulmonary vascular blockage. The goal of this study was to evaluate the performance of BGS and combined BGS+BT shunt in achieving the desired blood flow rate between the innominate veins and left and right pulmonary arteries by BGS and between right ventricle and left and right pulmonary arteries by BT shunt. Other important flow field parameters such as Wall Shear Stress (WSS) were also investigated, (2) Pulsatile blood flow in a flexible tube by considering the effect of Fluid-Structure Interaction (FSI) between the tube wall and the blood flow. Simulations for pulsatile flow in a rigid tube were also performed for validation against the well-known analytical Womersley solution, and (3) FSI simulation and validation of flow field of a cantilevered plate for which experiments were performed in the FLOTEK 1440 wind tunnel at different angles of attack and Reynolds numbers. Good agreement between the FSI simulations and experimental data was obtained. All three 3D models were created using CAD software SolidWorks. The meshing, computational setup and analysis were conducted using the commercial CFD software ANSYS Fluent, CFD POST and ANSYS Static Structural and data processing software with MATLAB and Microsoft Excel.
