Seminar Series 1/2009: (iii) Shear Stress and Flow Stability For Blood Flow In An Aneurysm

(iii) Dr Greg Sheard, lecturer, Mech. & Aerospace Eng, Faculty of Engineering, Australia.

"Aneurysm is a form of arterial disease characterized by a localized weakening and dilation of the blood vessel. Aneurysms seldom present symptoms, and are relatively common in the aged population. However, they can be fatal if they rupture, and are risky to repair surgically. A well-known link exists between the fluid mechanical stresses imparted on an artery and the integrity of the wall tissue; and our group is presently investigating the fluid mechanics within model aneurysm geometries to develop our understanding of the dynamics of these complex flows. In this seminar, measurements of wall shear stress are reported from pulsatile flow through a model aortic aneurysm, and a stability analysis is conducted on the flow to examine symmetry breaking in the flow."
