description |
The significant progress in computer innovation technique, computational fluid
dynamics (CFD) has been applied for real applications on patient-specific
hemodynamics and extensively used to study cerebral aneurysm rupture. In addition,
the computational study with representative blood vessel configuration has become a
great tool in providing comprehensive information on geometry, the flow field of blood
and wall shear stress (WSS). Generally, the numerical simulations have an expected
problem on the specification of the exact boundary conditions which leads to
unphysical numerical solutions. Therefore, this paper tends to find out whether CFD
simulation manages to obtain precise and better predictions of hemodynamics
patterns at present time especially for phase-contrast magnetic resonance imaging
(PC-MRI) in terms of the velocity flow field and WSS distribution. Several research
articles are included and their qualitative and quantitative results on hemodynamics
have been compared. Both MRI measurement and CFD simulation have reasonably
good agreement on velocity flow fields and a detailed spiral recirculating flow pattern
can be observed in CFD simulation as compared to MRI measurement instead.
However, CFD simulation has overestimated the WSS, especially at the maximum WSS
location. The CFD simulation is capable to achieve good agreement on velocity flow
fields with MRI measurement, yet the result for WSS distribution has to be further
improved and justified with consistent assumptions and techniques. |
