Newtonian and non-newtonian CFD models of intracranial aneurysm: A review

Computational Fluid Dynamics (CFD) has become an essential research tool to investigate the physical, biophysical and pathophysiological processes leading to the formation, growth and rupture of intracranial aneurysms (IAs). The diverse anatomical complexities of IAs dictate a staggering level of so...

description Computational Fluid Dynamics (CFD) has become an essential research tool to investigate the physical, biophysical and pathophysiological processes leading to the formation, growth and rupture of intracranial aneurysms (IAs).

From medical imaging to wall shear stress mapping on the aneurysm walls, there are numerous physical assumptions related to blood flow and wall dynamics.

This review is an endeavor to summarize, in a critical and comprehensive manner, the different assumptions used to calculate blood viscosity in CFD models of IA hemodynamics.
