The time-varying velocities of cyclic flows inside a rigid abdominal aortic aneurysm model (AAA) have been measured with a laser Doppler Anemometer. The results showed that only the flow around the distal neck of the aneurysm model would become turbulent during the deceleration phase of the simulated cardiac cycle. Other portion of the flow remained laminar at all times. Some possible accompanying physiological effects of flow transition in diseased arteries were subsequently discussed in the paper.
