CFD solutions under second-order discretization schemes of velocity magnitude versus time at a monitoring point in each of the 16 aneurysms in Fig. 4. (a) The eight unstable flow cases, which demonstrated persistent velocity fluctuations, and thus, high aneurysm-averaged fKE in the last three periods. (b) The eight representative stable flow cases, which showed no fluctuations, and thus, low aneurysm-averaged fKE.
