Abstract : Aneurysm is the bulging of blood vessels at specific locations like bifurcations and turnings. It is very essential to reveal the blood flow dynamics inside aneurysm to develop proper treatment and diagnostic methods. This paper analyses the effect of parent artery curvature on side-wall saccular aneurysm using CFD. Idealized spherical aneurysm models were studied with different parent artery curvature. Blood was considered as a non-Newtonian shear thinning fluid and a pulsatile flow velocity was provided at the inlet section. The variation in different hemodynamic parameters like Wall shear stress (WSS), Time average wall shear stress (TAWSS) and Oscillatory shear index (OSI) were studied for all models at the peak systole of the pulsatile wave. A reduction in WSS was observed with increase in parent artery curvature and the oscillations in WSS intensify with increase in curvature.
