Abstract This project is a proof-of-concept of a novel aortic valve for the human heart. It involves mathematical modelling spiral and pulsatile blood flow from the left ventricle into and through an artificial heart valve. The valve has three leaflets (or flaps) which open and close in accordance with systole and diastole. These large (elastic) deflections, driven by the pressure gradient of the blood, need to be modelled and numerically simulated in order to ensure that the valve opens and closes rapidly and the shear stress in the blood flow is always above a critical limit to avoid blood clotting. It is intended that the numerical technique to be employed is the immersed boundary method. A comparison with the standard current state-of-the-art valve will be undertaken. (AU) | |
