ON NON-NEWTONIAN EFFECTS IN CEREBRAL ANEURYSMS: A COMPUTATIONAL STUDY ON 12 PATIENT SPECIFIC ANEURYSMS

摘要

The non-Newtonian effects on WSS are clearly visible and could be regarded as significant. However, as Figure 2 shows, the variations with regards to geometry are far greater than the variations caused by the different viscosity models. When also considering the uncertainty in the model created by the assumptions made on boundary conditions and rigid walls, we believe that there are several other factors to be considered before the non-Newtonian effects can be deemed critical for an accurate solution of blood flow in cerebral aneurysms.
