Influence of the coiling porosity on the risk reduction of the cerebral aneurysm rupture: computational study.

The formation and progress of cerebral aneurysm is highly associated with hemodynamic factors and blood flow feature. In this study, comprehensive efforts are done to investigate the blood hemodynamic effects on the creation and growth of the Internal Carotid Artery. The computational fluid dynamic method is used for the visualization of the bloodstream inside the aneurysm.

Simulation of fluid flow in a body-fitted grid system using the lattice Boltzmann method.

The ability of the interpolation supplemented lattice Boltzmann method (ISLBM) diminishes in simulation of fluid flow around complex geometries and it is nearly impossible to use this method in body-filled grid systems. In this paper, a developed version of the interpolation supplemented lattice Boltzmann method is proposed to remove the limitations of the original ISLBM. Combination of the ISLBM and the Joukowski transformation is the basis of the method.
