Abstract

Mechanical properties of blood flow are commonly correlated to a wide range of cardiovascular diseases such as atheroma and aneurysms, and play a role in vascular remodelling. While the relationship between the flow field and disease are not fully understood, fluid mechanics parameters on and near the artery wall, such as wall shear stress and derived measures, residence times and region of flow impingement are among the most commonly sought correlators to disease. This is often discussed in relation to mechanotransduction and mass transport. Other measures are associated to disturbed, oscillatory or unstable flows. In this work means to describe and characterise the flow field in the free-slip and no-slip domains are discussed in the context of cerebral aneurysms reconstructed from in-vivo medical imaging.
